I have a quick question similar to this. So my ADF was perfectly normal a day ago, but I have woken up to it floating. I tried to nudge it to see if anything was wrong and it swam just fine, but it was still afloat. So I tried to see if he could sink down, so I pushed him down a bit and he just floated back up, as if against his will. So I was wondering if something is wrong, like if he has a disease or if he is dying. I have looked at many other websites to figure this out but none of them give any specific information. So could anybody tell me what is happening?
