55 gallon grow out tank all my peramiters are good in the tank. Tank mates are 2 birchirs and one sevrum that I though was a good idea bringing home from the pet store for free because it was in bad shape was going to quarantine but when I got home I realized something caused my quaritine tank to crash. The flowerhorn is still eating but I’ve noticed red bumps around his gills I’m really worried. Looks as if red marks are bleading through his scales. If someone could please identify what this is it and what to cure it with it would be greatly appreciated.
