Blunt-jawed Elephantnose Tank Setup

A tank of at least 650 litres (172 US gallons) works well. Keep the water at 73-82°F with a pH around 6.5-7.5, and set up both cover and open swimming space where they spend most of their time (Mid). They grow to around 40 cm, so plan the tank size and filtration for a full-grown adult rather than the small juvenile you see in the shop.

What Do Blunt-jawed Elephantnoses Eat?

They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.

Blunt-jawed Elephantnose Tank Mates

Requires a large tank and good filtration. The Blunt-jawed Elephantnose is peaceful, which is the first thing to weigh up when you choose tank mates.

It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.

Are Blunt-jawed Elephantnoses Good for Beginners?
