Crystal Red Shrimp Tank Setup
A tank of 30 litres (8 US gallons) or more with rock-steady water suits them best - keep it at 66-79°F with a pH around 6.5-8. Stable conditions matter most, as shrimp struggle to moult and breed when parameters bounce around.
What Do Crystal Red Shrimp Eat?
They're bottom feeders, so give them sinking wafers, tablets, or frozen treats like bloodworm once the lights go down. Flakes that never reach the bottom leave them hungry even when the tank looks well-fed.
Crystal Red Shrimp Tank Mates
Sensitive to copper and some medications. The Crystal Red Shrimp is peaceful, which is the first thing to weigh up when you choose tank mates. Good matches come down to the whole stocking list working together - temperature, tank size, and temperament - not any single label. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Crystal Red Shrimp Good for Beginners?
Reasonable early choice after cycling. Buy after the tank has stable ammonia and nitrite readings, not the same weekend you fill it.

Keep them at 66-79°F with a pH of 6.5-8, steady rather than chased to an exact figure. In a cycled tank, ammonia and nitrite should both read 0 ppm, with nitrate kept low through regular water changes.
