What is the Shrimp Tank Size Calculator?
The Shrimp Tank Size Calculator recommends minimum tank size in liters or gallons for keeping aquarium shrimp. Undersized housing is one of the most common and most fixable welfare problems in pet keeping, it affects everything from stress levels to exercise to litter/waste management.
Aquarium shrimp generally live 1-2 years when they are well looked after. As an omnivore, what a shrimp needs from its diet changes across its life stages. Aquarium shrimp are acutely sensitive to copper and to sudden parameter swings, and need a fully cycled planted tank. They are small enough to be eaten by most fish, so a species-only tank usually works best. Health problems that show up most often in aquarium shrimp include copper poisoning, failed molts from calcium imbalance, ammonia sensitivity, which is part of why tracking this over time pays off.

How does the Shrimp Tank Size Calculator work?
The recommendation is based on published care-guide minimums for aquarium shrimp, scaled to the animal's current or expected adult size. The math is only as good as what you feed it, so an accurate, recent input matters more than the formula itself.
Factors that matter
- Adult size: housing should be sized for the animal's full-grown dimensions, not its current size if still young
- Number of animals being housed together, since space needs don't simply divide evenly
- Activity level and natural behavior, such as climbing, digging or swimming space
- Whether the space is temporary (travel/carrier) or permanent (everyday housing)
How do you use the Shrimp Tank Size Calculator?
- Enter the adult body length in whichever unit you use (in, ft, cm)
- Answer "How many of this species?"
- Pick your filtration and planting (Standard filter, no live plants, Strong filter or heavily planted, Minimal filtration)
- Press Calculate, then read the result alongside the sources listed below
Bring the number to your next appointment. Vets can work with a figure and a date far more easily than with "he seems a bit off lately".

Before you rely on this
This calculation assumes a healthy adult shrimp with no complicating conditions. Pregnancy, recovery from illness, medication and significant age at either end of the scale all change what is appropriate. When in doubt, the safest move is to take the number to a vet and ask whether it fits your particular animal.
