I have a grown molly that I noticed wasn't swimming right a while back. He would swim slightly tilted, and when diving he would dive in fast spirals - usually until hitting the bottom of the tank.
After asking you guys for advice (http://www.aquariumadvice.com/forums...se-365856.html
) I ended up putting him in a bowl and feeding him peas for a couple of days. After that everything seemed back to normal, suggesting that it was a bad case of constipation. However, after a few days, the unusual behavior starts again, again I've treated it by putting him in the bowl and feeding him peas.
None of my other fish are showing any signs of disease, and the cycle continues. He gets sick, I feed him peas, he's fine for a couple of days, then gets sick again.
So, do you guys have any other suggestions for how to deal with this situation, other than me constantly moving this poor fish between tanks (or permanently leaving him alone in the small bowl)?
