Thanks what do I do with salt?that looks like a healing injury. probably the start of territorial disputes among the ranks there. Salt and clean water, he'll be fine.
they look good, move them on now to someone with AT LEAST a 250 gallon or 1000 litre tank to start. these fish need room. Also, make sure whoever you sell them to understands the size requirements and care needed for a single species fish. They won't be able to add friends lol.
And thanks for the info il definitely be looking out for someone with a big tank
