I have a betta, he is pretty old and he is in a 2.5 gallon tank. I noticed a few days ago that his scales were kind of pineconed, but he is acting fine otherwise. What do you think it is? I had a betta with pinecone scales a few years ago, but it died shortly after I noticed it. I noticed it a few days ago in this betta and he is still acting fine. What do you think it is?
