bettas and other fish

    if a betta lives in an aquarium with other fish,
    and those fish are dieing, can the betta catch the disease,
    or do different breeds of fish have their own different diseases?

    Some fish have their own diseases such as dwarf gourami iridovirus, but there are lots of diseases that can be passed from fish to fish regardless of species & infect the whole tank

    If a betta is in a tank with other fish and the other fish are dying, it's very possible the bettas is killing them. I would remove him immediately. If they are sick, he could get what they have, and if they are stressed and dying from that, he's the cause

    but what species of fish do most people have success when they are in a tank with bettas?

    Betta fish have personality much like a person, dog or cat. Some do fine with a companion some will kill their tank mates. they are predator's so its important to keep that in mind. Snails, ADF, and shrimp are the most recommended. Some people have success with other fish but once again it all has to so with the temperament and size of the fish in question. Bettas will always attack fish that resemble themselves as well.

    Unless you are an experienced betta keeper, I don't recommend keeping them with other fish at all. Snails are better tankmates (though many bettas will still kill them). Shrimp won't cause a problem, except that the betta will likely eat your shrimp.
