Budget Setup
5 Gallon Shrimp Tank Setup Under $50
A dedicated cherry shrimp nano (≈5 gallon / 20 L) without CO₂ or aquasoil. The core essentials — plain glass, sponge filter + air, clip LED, dechlorinator, inert sand, moss/Anubias — land around ~$48 if you skip plastic kits. An adjustable heater is optional (~+$12) and can push the cart near ~$60. We split the totals so “under $50” matches the math.
- Core ~$48
- + heater ~$60
- 5 gallon / 20 L
- Shrimp-first
- No CO₂
Core essentials ~$48 · With optional heater ~$60 (US Amazon estimates; prices move).
Complete shopping list (BOM)
How to read the totals: essential rows are the under-$50 shrimp path (~$48). The heater is optional — Neocaridina prefer stable warmth, but warm rooms often skip it. Buy order: tank → sponge filter → light → dechlorinator → sand → moss/Anubias. Do not add shrimp until ammonia and nitrite read zero (usually 1–3 weeks with bottled bacteria).
This list is shrimp-first — not a Betta share tank. For a general desk nano, see our nano aquarium setup under $50.
| Item | Why we pick it | Est. | Buy |
|---|---|---|---|
| 5 gal / 20 L rimmed glass tank (plain glass) | Stable footprint for a starter colony; avoid sealed plastic “betta kits” that trap weak lights. | ~$16 | Buy Now |
| Small sponge filter + quiet air pump kit | Non-negotiable for shrimp — safe intake, huge bio surface, gentle flow. | ~$10 | Buy Now |
| Clip-on LED (daylight / ~6500K) | Grows biofilm + moss; 6–7 hours is enough at the start. | ~$8 | Buy Now |
| Liquid dechlorinator (shrimp-safe / copper-free) | Chloramine kills shrimp fast. Read the label — skip copper-based medications entirely. | ~$3 | Buy Now |
| Inert sand or fine gravel (2–5 lb) | Easy to clean; dark sand shows shrimp colors better. Skip aquasoil on this budget. | ~$5 | Buy Now |
| Moss + one Anubias (or Java fern) allowance | Moss = grazing surface; Anubias/Java fern = stable epiphytes. One plant pack beats melting carpets. | ~$6 | Buy Now |
| Optional: 25W adjustable heater Optional | Add if nights drop below ~72°F / 22°C. Takes the cart to ~$60. | ~$12 | Buy Now |

What NOT to buy under $50 (shrimp edition)
- HOB filters with open intakes — shrimp get stuck; sponge filters win.
- Copper-based meds, snail killers, or “algae fixes” — copper is lethal to shrimp.
- Aquasoil + carpet plants + CO₂ tablets — melts and algae on a $50 shrimp budget.
- Sealed plastic kits with green LEDs — hard to clean; weak biofilm growth.
- Buying 20+ shrimp on day one into uncycled water — start 6–10 after 0/0 ammonia/nitrite.
- Betta “roommates” on this budget — many Bettas hunt shrimp; keep this list shrimp-only.
Common mistakes first-time shrimp keepers make
- Skipping the cycle — shrimp crash on ammonia spikes faster than hardy fish.
- Big water changes with unmatched parameters — drip-acclimate livestock; match temperature.
- Overfeeding “shrimp food mountains” — biofilm + tiny pinches; remove uneaten food.
- Running light 12 hours — algae blooms; start ~6–7 hours.
- Using tap water with unknown copper / softener salt — if unsure, use conditioned tap tested safe or remineralized RO later (upgrade tier).
- Buying a heater “just because” — only if the room gets cold; otherwise save $12 for a test kit.
Why this shopping list
Shrimp succeed on stable, gentle biology: sponge filtration, biofilm-friendly light, and copper-free water care. This BOM is a specialized cut of our nano under-$50 setup — same price honesty, shrimp-first stocking and gear rules.
Skip CO₂ and aquasoil until you want a higher tier (see $150 shrimp colony later). Before adding more than a starter group, run the stocking calculator as a sanity check — shrimp bioload is light, but oxygen and waste still matter in 5 gallons.
What fits this shrimp setup
- Livestock (after cycle): 6–10 Neocaridina (cherry / similar) to start; let them breed up. Skip Caridina/crystal shrimp on this budget (harder water needs).
- Plants: Java moss, Christmas moss, Anubias nana, Java fern — see easy aquarium plants 2026.
- Optional later: 1–2 Nerite snails (check copper-free food).
- Avoid: Betta, most community fish, goldfish, copper treatments.

Week-1 checklist (shrimp)
-
Day 0
Build & start the sponge filter
Rinse sand. Place a small wood/rock if you have it. Fill with dechlorinated water. Start sponge + air pump.
-
Day 0–1
Seed bacteria & short lights
Add bottled bacteria. Run light ~6 hours. Attach moss loosely so it can catch biofilm.
-
Day 2–5
Observe — no shrimp yet
Spot-clean debris. Do not feed. Cloudy water is often a temporary bacterial bloom.
-
Day 5–7
Test if you can
Check ammonia/nitrite. 20% water change only if very cloudy — match temperature.
-
Week 2+
Add shrimp when 0/0
When ammonia and nitrite read 0, drip-acclimate 6–10 Neocaridina. Feed tiny pinches after 24 hours.
Spend-next upgrades
- API Master Test Kit or reliable strips — Biggest jump — know when 0/0 before buying shrimp (~$20–35)
- Indian almond leaves / botanicals — Extra biofilm and gentle tannins shrimp enjoy (~$8–12)
- Better nano LED bar — More even moss growth; re-check with light calculator (~$25–40)
- Next tier: shrimp colony ~$150 — More volume, remineralization options, denser plant mass (BGT-150-SHRIMP) (Tier up)
FAQ
Can I stay under $50 for a shrimp tank?
Yes on the core path (~$48): glass, sponge kit, clip LED, dechlorinator, sand, moss/Anubias — no heater. The optional heater (~$12) is why carts often land near $60.
How many shrimp in 5 gallons?
Start with 6–10 Neocaridina after a full cycle. They breed up; avoid dumping 30 into fresh water.
Do shrimp need a heater?
Only if nights drop below ~72°F (22°C). Stable warmth helps breeding; warm rooms can skip it.
HOB or sponge filter?
Sponge only on this budget — safer and better biofilm for shrimp.
Can I add a Betta later?
Risky — many Bettas hunt shrimp. Keep this build shrimp-only, or use a larger dedicated shrimp tank.
Crystal / Caridina shrimp on $50?
Not recommended. Stick to hardy Neocaridina until you can control GH/KH more precisely.
