How Many Cherry Shrimps in a 5 Gallon Tank?
Too small for a healthy school — based on adult size, bioload, and real water volume.
A 5-gallon tank is really too small for a proper group of cherry shrimp — they're a schooling fish that needs at least 5 to feel secure. Step up to a bigger tank, or pick a smaller schooler.
How we get that number
An adult cherry shrimp reaches about 1.5" and has a low bioload. Working from real water volume and waste output (not the old one-inch-per-gallon myth), a 5-gallon tank supports roughly too small for a healthy school of them. Because cherry shrimp are schooling fish, keep them in a group of at least 5 — never just one or two. They need 65–80°F water at pH 6.5–8.
