I added three medium silver dollars to my tank about three days ago and they have all settled in fine now, except I noticed this morning when I turned the tank lights on that one of them (the biggest) now seems to have swim bladder issues?
It basically swims in circles, trying to swim downwards in desperation. If it stops swimming it starts to float towards the surface. Poor thing must be tired from continuity having to swim. The other two are swimming normal.
Any ideas? I was thinking of trying the de-shelled pea trick for constipation, incase that's the problem... :-?
