I’ve had this fish for a few weeks. It was swimming and eating fine, nice and healthy. A few days ago I noticed it’s not coming out, saw it was injured, most likely by my blue angelfish which is now been housed at the LFS. I removed my injured fish yesterday in a 5 gallon tank, added one dose of Kanaplex, air stone, heater. No filter, figured I’d just do WC, every couple days to avoid any contamination from filters etc. Jt hasn’t been eating since it got injured. Am I correctly treating it? Is Kanaplex good for injuries/infections that can happen due to injuries. Should I dose twice, I believe I can “safely” give 3 doses or also a dose every two days until better. I also have API general cure or am willing to buy anything you recommend. First time treating an injured fish, any and all help appreciated!
