He has been kinda lethargic lately. He normally sleeps at the top of the tank, but has been sleeping towards the bottom. I was able to get him an actual tank now. It is only 1.5 gallons, but it has an air pump, filter, and I am still using his heater. I gave him about .5 of the recomended dose of Melafix because I thought he had pop-eye. I am not sure though because his eye isn't massive how I see in some example pics I saw the other day. He has had bouts with finrot, ick, fungus, malnutrition, and depression. Since I rescued him these have gone away. His fins are still a bit clamped and his color has not came back completely. I got him about 5 and a half months ago. I use Jungle start right, and Tetra Easybalance in his water. He has 1 plant, sign, and sea shell as decorations. I alternate feeding him BettaMin Tropical Medley, Freezedried bloodworms, and TetraBetta Tropical flakes.
The only recent changes to his environment is his filter and pump. Also he went from a 1 gallon to a 1.5 gallon tank. This was Yesterday.
