How to Set Up a Shrimp Tank on a Budget

Last updated: February 2026 | 12 min read

You don't need to spend hundreds of dollars to keep shrimp. Some of the most successful colonies out there started in cheap tanks with basic equipment. The shrimp don't care about your budget - they care about stable water and a few places to hide.

We'll break down exactly what you need, what you can skip, and where to save money without cutting corners on shrimp health. Whether you're a college student, a parent testing the waters, or just someone who doesn't want to blow $200 on a hobby you're still figuring out, this guide is for you.

What Do Shrimp Actually Need?

Before we talk prices, let's get clear on the non-negotiables. Shrimp need:

• •A tank (obviously)
• •A cycled filter
• •Some kind of substrate
• •A few hiding spots
• •Stable water parameters
• •A light source (even basic)

That's it. No CO2 injection. No fancy canister filters. No rimless designer tanks. The shrimp living in $500 setups aren't any happier than ones in a $40 setup with good water quality.

The Budget Breakdown

Here's a realistic budget build that real shrimp keepers on r/shrimptank have used successfully:

Okay, that's a bit over $50 if you buy everything new. But there are ways to shave costs, which we'll cover below.

Not included: The shrimp themselves ($1-5 each depending on species and grade) and the test kit, which many keepers already own.

Tank: Go Standard, Not Fancy

Best budget option: Standard 5 or 10-gallon glass tank ($12-20)

Skip the all-in-one kits. As one r/shrimptank user put it: "I got a Top Fin Shrimp and Plant Oasis for $39 then ended up replacing the filter, then the light, then when two batches of shrimp died off on me I replaced the tank completely."

Kits bundle cheap components you'll eventually replace. A basic glass tank from a pet store costs less and lasts forever.

Money-saving tips:

• •Dollar-per-gallon sales at Petco happen several times a year. A 10-gallon for $10 is hard to beat.
• •Facebook Marketplace and Craigslist are gold mines. People give away tanks constantly. Just inspect for cracks and clean thoroughly with vinegar (never soap).
• •A 10-gallon is actually better for beginners than a 5-gallon. More water volume means more stable parameters, and they're often the same price during sales.

What about smaller tanks? You can keep shrimp in a 2.5-gallon, but smaller tanks are harder to keep stable. If you're on a tight budget, a larger tank is actually the cheaper long-term choice because parameter swings kill shrimp, and replacing dead shrimp adds up fast.

Filter: Sponge Filters Are King

Best budget option: Sponge filter + air pump ($8-12 total)

Sponge filters aren't just the budget option for shrimp - they're the best option at any price point. Here's why:

• •Shrimp-safe: No intake to suck up babies
• •Biological filtration: The sponge surface area grows beneficial bacteria
• •Grazing surface: Shrimp love picking at the biofilm that grows on sponge filters
• •Dead simple: No moving parts to break, no cartridges to replace
• •Quiet: Just a gentle bubbling sound

You need two pieces: the sponge filter itself ($3-5) and a small air pump to drive it ($5-8). Add a few feet of airline tubing and a check valve, and you're set.

Hikari Bacto-Surge Sponge Filter - a reliable pick that runs about $5.

Tetra Whisper Air Pump - quiet and cheap for tanks up to 10 gallons.

Skip the hang-on-back filters. They work fine for fish, but baby shrimp get sucked into the intake. If you already own one, you can cover the intake with a sponge pre-filter, but why bother when a dedicated sponge filter costs $5?

Substrate: Skip the Fancy Stuff (for Neocaridina)

Best budget option: Pool filter sand or lava rock ($5-8)

If you're keeping Neocaridina shrimp (cherry shrimp, blue velvets, yellow shrimp), you don't need expensive aqua soil. These shrimp are adaptable and do fine in most tap water.

Cheap substrate options that work:

• •Pool filter sand ($8 for a 50-pound bag at a hardware store - enough for 20 tanks)
• •Black Diamond blasting sand (~$10 for 50 pounds, gives a nice dark look)
• •Lava rock gravel ($12 for a large bag, great biological filtration surface)
• •Plain aquarium gravel - works fine, just harder to spot baby shrimp

One user on r/shrimptank broke down their entire budget setup: "Tank: $25. HOB: $25. Lava rock substrate: $12. Plants: $2-5 each. Seachem Prime: $10. 20 Fire reds: $20. Light: $15."

When you DO need aqua soil: If you're keeping Caridina shrimp (Crystal Red, Taiwan Bee), they need acidic, soft water. Buffering substrates like ADA Amazonia or Controsoil actively lower pH. But Caridina aren't budget shrimp anyway - they're $5-15 each and much less forgiving. Start with Neocaridina.

Plants: Free or Nearly Free

Best budget options: Java moss, floating plants, Pothos cuttings ($0-10)

Plants do real work in a shrimp tank. They absorb nitrates, provide hiding spots, grow biofilm for shrimp to graze on, and give baby shrimp places to hide from everything (even though nothing in the tank is trying to eat them - shrimp are just cautious like that).

The cheapest plants for shrimp tanks:

• •Java moss ($5-8 for a golf ball-sized portion): Grows on anything, provides excellent hiding spots for babies. This is the #1 recommended plant for shrimp tanks across all experience levels.
• •Floating plants (free from other hobbyists): Duckweed, frogbit, water lettuce. These multiply like crazy. Check r/aquaswap or local fish groups - people literally give these away because they can't get rid of them fast enough.
• •Pothos cuttings ($0 - someone you know has a pothos): Stick the roots in the water, keep the leaves above. Pothos is a nitrate vacuum. It's not a true aquatic plant, but it works brilliantly in shrimp tanks.
• •Marimo moss balls ($3-5 each): Low-maintenance, shrimp love picking at them. Just roll them occasionally so they keep their round shape.

Free plant sources:

• •r/aquaswap: People regularly post free floating plant giveaways (you pay shipping, usually $5-8)
• •Local fish stores: Ask if they have plant trimmings. Many will give you a bag of clippings for free.
• •Local aquarium clubs: Facebook groups for your area almost always have members giving away plant cuttings

Skip CO2 injection. The plants listed above are all low-tech and grow fine under basic lighting with no added CO2. That's $100+ saved right there.

Lighting: Keep It Simple

Best budget option: Desk lamp with LED bulb ($0-10) or clip-on aquarium LED ($12-20)

Shrimp don't need special lighting. They actually prefer dimmer environments. The light is mostly for your plants and for you to see the shrimp.

Budget lighting options:

• •A desk lamp you already own with a 6500K daylight LED bulb ($3 at any hardware store). Clamp it above the tank. Done.
• •Clip-on LED aquarium lights run $12-20 on Amazon and work great for tanks up to 10 gallons.
• •A sunny window provides free light, but be careful - direct sunlight causes algae blooms and temperature swings. Indirect light near a window works fine.

NICREW ClassicLED Aquarium Light - one of the most popular budget lights. Around $15-20.

Run lights 6-8 hours a day. More than that encourages algae. Use a $5 outlet timer so you don't have to remember to turn it on and off.

Heater: You Might Not Need One

Cherry shrimp and most Neocaridina do fine at room temperature (65-78°F / 18-26°C). If your house stays in that range, skip the heater entirely.

When you need a heater:

• •Your house drops below 65°F regularly
• •You're keeping tropical species like Caridina
• •The tank is in an unheated garage or basement

If you do need one, a small preset heater runs $10-15. Check out our full guide on whether shrimp need a heater for more details.

Water Conditioner: The One Thing You Can't Skip

Seachem Prime ($5-7 for a bottle that lasts months)

Tap water contains chlorine and chloramine, both of which kill shrimp. You need a dechlorinator. Seachem Prime is the standard recommendation because:

• •It neutralizes chlorine, chloramine, and heavy metals
• •It temporarily detoxifies ammonia and nitrite (helpful during cycling)
• •A tiny amount treats a lot of water (2 drops per gallon)
• •A $5 bottle lasts most shrimp keepers 6+ months

Seachem Prime on Amazon - the single most recommended product in the shrimp hobby.

Test Kit: The Boring Purchase That Saves Lives

API Freshwater Master Test Kit ($20-25)

This is the most expensive single item on the list, and it's the one you absolutely cannot skip. Without testing your water, you're guessing. And guessing kills shrimp.

You need to test for:

• •Ammonia (should be 0 ppm)
• •Nitrite (should be 0 ppm)
• •Nitrate (under 20 ppm)
• •pH (6.5-7.5 for Neocaridina)

The API Master Test Kit includes all of these and lasts for hundreds of tests. The $20 you spend here will save you from spending $40 replacing dead shrimp because your tank wasn't cycled.

API Freshwater Master Test Kit - don't buy test strips, they're inaccurate.

Pro tip: If you're really strapped for cash, some local fish stores will test your water for free. Just bring a sample in a clean container.

Cycling: The Free Step Most Beginners Skip

This part costs nothing but time, and it's where most budget setups fail. You MUST cycle your tank before adding shrimp. No exceptions.

Cycling means growing beneficial bacteria that convert toxic ammonia into less harmful nitrate. It takes 4-6 weeks. Here's the short version:

1. •Set up your tank with substrate, filter, and plants
2. •Add a pinch of fish food every few days (this produces ammonia)
3. •Test water every 2-3 days
4. •When ammonia and nitrite both read 0 ppm and nitrate is present, your tank is cycled
5. •Do a water change, then add shrimp

We have a full guide on how to cycle a shrimp tank if you want the detailed walkthrough.

Budget cycling tip: Ask a local fish store or a friend with an established tank for a piece of used filter media. Squeeze it into your tank water or place it in your filter. This seeds your tank with bacteria and can cut cycling time in half.

Where to Save Even More

Already at your limit? Here are some tricks experienced keepers use:

Get shrimp from hobbyists, not pet stores. Local breeders on r/aquaswap, Facebook groups, and aquarium club meetings sell cherry shrimp for $1-2 each - sometimes less for bulk. Pet stores charge $4-6 for the same shrimp. Buying 10 cherry shrimp from a breeder at $1.50 each ($15) versus a pet store at $5 each ($50) saves $35 right off the bat.

Use what you have. A clean glass jar, food-safe container, or even a large vase can technically house a few shrimp temporarily. Not ideal long-term, but it works while you save up for a proper tank.

DIY hides from stuff in your kitchen. Shrimp love hiding in:

• •Terracotta pot pieces (boil first)
• •PVC pipe sections
• •Ceramic mugs (food-safe, no paint)
• •Coconut shell halves (available cheap or make your own)

Tap water is free. One of the biggest advantages of Neocaridina shrimp - they adapt to a wide range of tap water parameters. You don't need RO water, remineralizers, or any of that. Just dechlorinate and go.

Sunlight is free light. Position your tank near a window with indirect light. Just avoid direct sun hitting the tank - that causes temperature swings and algae explosions.

The Complete Budget Shopping List

Here's the no-nonsense shopping list for a functional shrimp tank under $80 all-in:

1. •5-gallon tank - $10-15 (or free from marketplace)
2. •Sponge filter - $4-5
3. •Air pump + airline tubing - $6-8
4. •Pool filter sand - $5 (you'll have 49 pounds left over)
5. •Java moss - $5-8 (from r/aquaswap or local store)
6. •Seachem Prime - $5-7
7. •Desk lamp + daylight bulb - $0-5 (probably already own one)

Total: $35-48

Add the API test kit ($20-25) if you don't have one, and 10 cherry shrimp from a local breeder ($10-20).

Grand total to get started: $65-93

That's a fully functional shrimp colony that will breed and grow for years. The ongoing cost is practically nothing - a pinch of food every few days and occasional water conditioner.

Common Budget Mistakes to Avoid

Skipping the cycle. We said it already, but it bears repeating. A "budget" setup that kills $30 worth of shrimp because you didn't wait 4 weeks isn't actually saving money.

Buying cheap test strips instead of the liquid kit. Test strips are $10-12 and wildly inaccurate. The liquid kit costs $10 more and gives you reliable results hundreds of times. Math.

Overstocking too early. Start with 8-10 shrimp. If your setup is healthy, they'll breed. In 3-4 months you could have 50+ shrimp without buying any more. Patience is the cheapest way to stock a tank.

Skipping water conditioner. Some people try to "save" by letting tap water sit out overnight to off-gas chlorine. This works for chlorine but NOT for chloramine, which many water treatment plants use. Chloramine doesn't evaporate. Spend the $5 on Prime.

Putting the tank in direct sunlight to avoid buying a light. Indirect sunlight near a window is fine. Direct sun on the tank causes temperature swings of 5-10°F, algae explosions, and stressed shrimp. A $3 LED bulb is worth it.

Monthly Maintenance Costs

Once your tank is running, the ongoing cost is almost nothing:

• •Food: A can of shrimp food lasts 6-12 months ($8-12)
• •Water conditioner: A few drops per water change, bottle lasts months ($5-7 per year)
• •Electricity: A sponge filter air pump and small light run about $1-2 per month
• •Water changes: Free (just tap water and Prime)

Total monthly cost: Under $5

That makes shrimp keeping one of the cheapest pet hobbies around. Cheaper than a cat, a dog, or even most houseplants if we're being honest.

Bottom Line

You don't need permission from your wallet to start keeping shrimp. A basic 5-gallon setup with a sponge filter, some java moss, and a handful of cherry shrimp costs less than dinner for two. The shrimp will breed, the colony will grow, and in a few months you'll have a thriving tank that cost you next to nothing to maintain.

The only thing you can't cheap out on is patience. Cycle your tank. Test your water. Add shrimp slowly. Do those three things and your budget setup will outperform plenty of expensive ones.

Frequently Asked Questions

◆What is the cheapest way to start a shrimp tank?

Start with a basic 10-gallon tank, sponge filter with air pump, and inert sand substrate. Skip expensive active soils if keeping Neocaridina. Use Java moss and Java fern from online swaps. Total setup can cost under $50 with patience.

◆Are shrimp expensive to keep?

Shrimp are one of the cheapest pets to maintain. After initial setup, ongoing costs are minimal. They eat very little, have low bioload, and breed freely. A bag of shrimp food lasts months, and water conditioner is your biggest recurring expense.

◆What is the cheapest shrimp to buy?

Cherry shrimp are usually the most affordable at $2-4 each, or even cheaper when bought in bulk. Ghost shrimp cost as little as $0.50 each but have shorter lifespans. Buy from local breeders or r/aquaswap for the best deals.

◆Do I need CO2 for a shrimp tank?

CO2 injection isn't necessary for a shrimp tank. Low-tech plants like Java moss, Anubias, and Java fern grow well without it. Skipping CO2 saves money and avoids pH swings that can stress shrimp.
