Hello I am very knew to this website as in like ten minutes ago. So I barely know how to use it. Yesterday I had gotten a pictus catfish and today I noticed that his his one fin is frayed and has a little white on it. I don't know if this will help but at the store I noticed he was getting picked on and his whiskers are bitten off so only a centimeter or two remains. I don't know if he has fin rot or it is like that from other fish bitting him. Also I would like to know if my fishes whiskers will ever grow back. Thanks for the help.
