Spotted Raphael Catfish Tank Setup

Plan for at least 150 litres (40 US gallons) with soft sand or smooth, rounded gravel - sharp substrate wears down their delicate barbels. Keep the water at 72-79°F with a pH around 6-7.8. They reach about 15 cm as adults, so don't be misled by the small juveniles sold in stores.

What Do Spotted Raphael Catfish 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.

Spotted Raphael Catfish Tank Mates

The Spotted Raphael Catfish 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 Spotted Raphael Catfish 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.

Spotted Raphael Catfish - frequently asked questions

What size tank do Spotted Raphael Catfish need?

Spotted Raphael Catfish need a tank of at least 150 litres (40 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 Spotted Raphael Catfish need?

Keep them at 72-79°F with a pH of 6-7.8, 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 Spotted Raphael Catfish eat?

Spotted Raphael Catfish 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 Spotted Raphael Catfish good for beginners?

Yes - Spotted Raphael Catfish 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.

Common mistakes with Spotted Raphael Catfish

  • Underestimating tank size - the minimum footprint is 150 litres (40 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
