Ok so my baby plackat has been with us about 4 weeks and has been great. Three days ago I noticed that he was having a hard time swimming as if he kept floating to the top and couldn't stay down and was using alot of energy. I have been keeping my eye on him but today he took a turn for the worse. When I got up he was on his side but still breathing. I don't see that he has anything particular wrong as in spots or Ich. I fed him and he ate happily this morning.
Then I watched him swim down to his cave but its as if he is fighting a current but there is no filter in his tank. Currently he is in a QT tank with Epson Salt but his regular tank is as follows:
2 gallon, heated to 78-80, with silk plants and a cave. He eats pellets of 3 twice a day. I change his water 50% one time a week and 100% one time a week. I use Jungle conditioner and Tetra Right start each water change. All my other fish are fine and healthy and have the same regimen. He is always reconditioned to the new water for 20-40 min.
Any ideas? I thought maybe SBD and I think maybe I have been over feeding him since he is so small. All my other fish are big and grown, he is the only baby we have had. Is there something I did wrong?
