Hi, im in desperate need of help!!! I bought a mangrove jack about 4 weeks ago now and is currently around 15cm in length. He is in a 180gallon 6x2x2 tank with a redbay snook, pbass, 4 silver dollars and a sailfin pleco. The snook and pbass are around the same size. The mangrove jack was doing really well eating and swimming around like crazy and no signs of any bullying from him or any other fish. I went away for a few days over the Easter break and just came home and noticed he was really pale in colour stomach looks a little swollen and when swimming he would just drift around nose facing upwards with tail twirling underneath. I also noticed his fins and tail have been torned up a bit, I also noticed when he got close to a few silver dollars they chewed on his top fin and he just tokk it twirling around, which straight away raised alrm bells. He is the biggest and thickest fish in the tank other than the pleco and couldn't belive my eyes when I seen the silver dollars chewing on his fins!! I straight away did a 40% water change and put a divider up to seperate him from the other fish. I also put some aquarium salt in the tank to help in case of an infection and to help with the fins.
Its been a couple hours now and at times he looks like he is doing ok and has some control of his swimming, but every now and then when I look back over at the tank he would be whirling around at the surface of the tank!!
Is there anything else I can do? I have a male dovi about 18cm in a 90 gallon. Should i swap the two around while I have the divider up and treat the 90 gallon as a quarantine tank?
