Setting Up Betta Tank

I just got a 40 gallon tank that I’m going to use for a betta. I know I want to do sand substrate and plants but I was hoping for some suggestions on tank mates for my betta . I know most fish are out of the question but I’d like him to have some company in there.

are you going to do a betta sorority, or just have one in there? that will help determine stocking .

they seem to ignore my glowlight tetras and emerald cories. But basically you want to have dull colored slow swimming fish.

Ok that’s what I’ve read so far. Thanks

In a 40 you have a little more leway and options than in a smaller tank but you still have to steer clear of larger more aggressive fish and nippy ones.

I'd reccomend a large school - like 20 - of one of the boraras species. The great thing is that ib the wild the range of the betta and some bororas species tend tI overlap.

For me personally, I think the whole 'betta will kill other fish' is highly overrated. Having kept multiple males, they rarely get more aggressive than a chase - a few of my males were territorial and wouldn't allow other fish in his territory (around 8 inch in diameter - but would patrol the rest of the tank without trouble.

Good fish to mix would also be kuhlies - biotopically correct... - and cories as well. Fish that stay in the lower levels are usually fine - tetras, cories, loaches, rasboras - and they usually ignore them as well. Best bet is to stay away from surface dwelling fish - guppies, hatchets and gouramies - and some bettas are prone to having problems with fish with large finnage - like guppies - or brightly coloured - some tetras, or guppies.... but from my experiences, it is not the case.


I think my 'success' could also be due to introducing the betta after all my other fish, so the tank mates were already established and not coming into 'his territory' - aka the tank.

Thank you for all the great information. I’m a big fan of Cory so I think I’ll be going with them or the kuhlI loaches.
