Hi guys, I am new to this forum and i need help ASAP! I housed my green arow with a royalknife fish and they got along for 3 months already and yesterday morning i wake up to see my green arow with all his fins broken or frayed, his back and head all scratched up, and stopped eating. I moved the knifefish to my other tank, cleaned my tank and did a 50% water change, added salt. But the fins looks worst than before now...like its decaying or some sort. Help PLEASE!
. An injured aro is an injured aro. You have different treatment for different levels of injury???
