Shamgo: My understanding is that while bettas can spend prolonged periods of time in oxygen poor environments, or trapped in pools left when water levels are down, they don't spend their whole lives there. they do have to get out and meet each other to keep the species going. I always thought the rule of thumb was 5 gal min for bettas, but bettatalk says 1 gallon. there's what the fish will put up with and what's minimal to make the fish happy. I've seen bettas last way longer than I expected in tiny bowls, but they're lethargic and don't repond much to mirrors or people. What I like about anabantids is that they've got a little personality. Unfortunately, that personality is often "troublemaker". When they've got a little room to swim, they seem to exhibit the personality a bit more. You didn't say how big the bowl is, but if you've got a couple of gallons and put some moss (I'm thinking you might have some) in there for it to hide behind, it could be okay. I have more personal experience with paradise fish, having bred them back in the day, and now having the one you gave me. They're hardier than bettas, meaning that they seem impervious to shitty water, and they seem to stay more active in small containers. But again, it's clear that they like room to swim. As long as you have a stable room temp, you also don't have to worry about a heater. Of the 4 you gave me, I tried one in the cichlid tank, and it lasted one night. I gave one to a co-worker, and he loves it, in a 10 gallon eclipse with a few corys. I left the other two in a 3 gallon hex for a few weeks trying to figure out what I was going to do to separate them, thinking that, as juveniles, they wouldn't kill each other yet. I was wrong. So I put the one that's left in my own 12 gallon eclipse. I haven't figured out what else to put in there. It's kind of a crapshoot whether or not you get a killer or one friendly enough to put up with other fish. You could have that guy back if you want, and I could put more friendly fish in the eclipse. _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
