Elmo has a 6.5 gallon tank and he doesn't use it very much, he likes to stay at the bottom under the beer bottles or on top of the filter but he does blow bubblenests every week.
Clark Gable has a 4 gallon tank and I know he would prefer the 6.5 because he is quite an active little fish but he has never blown a bubblenest without a female in sight.
Anyway, they are both tailbiters and I was just wondering if the switch in tanks would be a bad idea? they could love their new homes but they may also get stressed and bite their tails again.
What do you guys think, good or bad?
