Tequila Splitfin Tank Setup

A tank of at least 75 litres (20 US gallons) works well. Keep the water at 64-75°F with a pH around 7-8.5, and set up both cover and open swimming space where they spend most of their time (Mid). Always keep a group of at least 5 of their own kind - kept alone or in pairs they tend to turn shy, nippy, or wash out in colour.

What Do Tequila Splitfins 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.

Tequila Splitfin Tank Mates

Endangered species; males territorial The Tequila Splitfin is semi-aggressive, which is the first thing to weigh up when you choose tank mates. It's a known fin-nipper, so avoid bettas, guppies, and other slow, long-finned fish. It's a shoaling fish, so settle a group of 5 or more of its own kind before adding anything else - a stressed, lonely fish is far more likely to nip or hide. 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 Tequila Splitfins Good for Beginners?

Doable once you test water regularly and catch problems before fish look sick. If this is your first tank, pick something more forgiving and come back later.

Common mistakes with Tequila Splitfins

Buying fewer than 5 - Tequila Splitfins need a proper school to feel secure; isolated individuals hide, fail to colour up, or become stressed.
Mixing with long-finned fish - Tequila Splitfins will nip at bettas, angelfish, and other fish with flowing fins, causing stress and infection risk.
