Rili Shrimp Tank Setup
A tank of 20 litres (5 US gallons) or more with rock-steady water suits them best - keep it at 59-84°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 Rili 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.
Rili Shrimp Tank Mates
Sensitive to copper and some medications. The Rili 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 Rili 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.
Rili Shrimp - frequently asked questions
What size tank do Rili Shrimp need?
Rili Shrimp need a tank of at least 20 litres (5 US gallons). A bigger tank is always easier to keep stable, and gives them more room to settle in and behave naturally.
What water parameters do Rili Shrimp need?
Keep them at 59-84°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.
What do Rili Shrimp eat?
Rili Shrimp are bottom feeders. Give them sinking wafers, tablets, and frozen foods that settle on the substrate, ideally after the lights go off. Feed small amounts once or twice a day, and remove anything they don't eat.
Are Rili Shrimp good for beginners?
Yes - Rili Shrimp are a reasonable beginner fish once the tank is cycled and parameters are stable. Add them after ammonia and nitrite read 0 ppm, not the same day you fill the tank.
