New to aquariums, have had a 5 gal
fluval chi tank for 3 weeks now.
Important to note that I did not know what I was doing and didnít wait to cycle the tank before adding fish, but it is cycled now. I was very careful to monitor all the levels required for my platys and tried to keep the tank conditions healthy while it cycled and did about a B+ job but was learning as I went.
Originally had three platys in the tank but one started bullying the other two and drove one of them to hide in the corner and also to stop eating. Removed the bully but the one fish still hides in corner and wonít eat after 4 days. I started adding API Pimafix in case the fish was sick although it didnít show any signs of fungus or bacteria or anything. The fish now moves around more and has more energy but still wonít eat and spends most of its time in the top corners of the tank.
Itís been about 8-9 days and Iíve seen it nibble food maybe twice in total and I feel the fish will die. Iím assuming either being in the tank while it cycled or the bully fish stressed it too much. But the other fish in the tank is happy and active and hungry and went through the same stuff and is doing good (bully fish was looking good too while in the tank). Just looking for advice in general on what to do with sick fish and any tips and tricks for bringing one back.
