Does he have fin-rot? He was really hurt when packaging and putting moving him into the other tank. some scales came off and his mouth kinda got hurt. He ate some arowana pellets the 3 days ago, than 2 days ago he started to spit it out every time i fed. and yesterday I noticed the messed up fins on the tail and the mouth got whiter and worse. he isnt eating...anything. no shrimp or the pellets. Really scared now, is he gonna make it? Water parameters are perfect. I added 4 table spoons of salt. Water is perfect and is always kept perfect. 40g sump added as well. he is 17 inches. Should I keep the water changes and keep adding salts or go to medications? THANKS!
