I disagree on this. Bettas and mollies shouldnt be together. Mollies prefer hard water while bettas perfer soft waters.Fish do not grow to the size of their tank; that's an old wives' tale. Gobies are active fish, and an active 3.5" fish is not OK in a 10 gallon tank. Bettas and gouramis that size do fine in small quarters because they are inactive fish and don't slam headfirst into the glass or get stressed out because they are cramped.
So- nix on the goby. Mollies are fine tankmates for your betta (though you may end up with more fry than your betta can eat), as are small short-finned tetras and cories. An apple or mystery snail might be all right too.
Oh...good. I was really worried. Still kind of am. Especially about the food stuff. My female betta has a problem with that in the 30 gallon. She actually just eats the tetra's food...stupid betta.We have plenty, plenty of people here who keep male bettas in community tanks . The fact that they don't do well is a myth. As long as the tank is understocked and the betta has the right temperament, they actually thrive a lot more than in a small tank. Even if the betta is territorial, they benefit extremely from the space. Bettas do not come from small puddles in the ground, they come from rice paddies, a rather large, though shallow, ecosystem, and they have been bred in captivity for many generations. While they can survive and thrive in small containers, these are intelligent animals and most of the members here prefer to give them space.
Karl, my water is in the 7.6 range, I've had bettas live 4-5 years.Then again, those were veiltailed and plakats.
Oh NO NO NO NO!!!!Lindz,
I would not keep my male betta together with other fish in a 10 gal. First, other fish might nip on it's tails (no more crown of half moon to admire. LOL). Why not separate you beta on a small container (one or 2 gal. alone) so you can admire it's color, fins, etc and control it's diet. On bigger tank, it tends to hide and might will not eat at all(other fishes will grabs it's food). Bigger tank which I use for female betta to grow until I pair them for breeding. Or get a betta tank divider or appartment where you can put up to 4 male betta. If you want other fishes, start a community tank separately. Most of the time, Male betta do not do good in community tanks. They tend to hide or stay on one corner.
Just my opinnion.
I got some Wardley Betta Food which is floating balls of food. They are very hard and they float and expand and soften when they are soaked. I always soak them. The betta loves them and they don't fit into the mouths of the platies or SAEs. Perfect solution. When I feed freeze dried bloodworm they all get some.Oh...good. I was really worried. Still kind of am. Especially about the food stuff. My female betta has a problem with that in the 30 gallon. She actually just eats the tetra's food...stupid betta.
