Hello, I have recently purchased a Niger Trigger from my LFS. For the first few days he was doing great, eating well and swimming everywhere. Yesterday he seemed to be in very bad shape, he was behaving very weirdly, both using the rocks to scratch himself and swimming very erratically. Today I noticed that their are a lot of black spots on his fins, and they are deteriorating very quickly. Today he's also just parking himself under a rock and it's getting me very worried. Does any1 know what this might be?
