I have 2 fish showing white marks. My blue Aceii hasn't been eating going on 3 weeks now, but is active for most part, he developed white marks on his face and was hiding in a cave(normally never in a cave, same day baby fry starting showing up). This happened 1 day after my convicts had 100-150ish babies in the corner. Which made my tank highly aggressive. The mother is an original to the tank, I added 1 male convict and another 1-female convict around same time my Aceii stopped eating. But the white marks did not appear until just 4 days ago. I since removed all the baby fry, ones that were in tank were eaten by the other fish(seems she gave up on her mother duties once I removed the fry. Did this mostly because of seeing my Aceii). Then same day I seen my tank come back to life and less hostile, looked normal the next day to. Then today my Bumblebee in the video link, is all messed up... He was fine just 2 days ago, I didn't see him to eat yesterday. Then saw him like you do in the video once I got home from work.
I don't know what it is. If its a sickness or from aggressive nipping?
Would appreciate any help, thank you. I have seen the male convict bully off my fish but nothing to hard, the male convict is still juvenile as well. My female convict has never been aggressive, but she was when she was protecting her fry. But my bumblee wasn't messed up when I removed the fry.
Water parameters: Trace amounts or nothing of ammonia/nitrite. Then 10-15ish ppm
nitrate. PH at a constant 7.8. Its a 60gallon tank with 6 cichlids of different lakes, but I hadn't had an issue in over a year now, till now.
