    About two week ago a purchased a beautiful vailtail. Since I got him he has had issues with his fins. He has a bit of a tail curl, but I am going to buy a britta filter to help with hardness.

    So Sebastian was swimming happily before I went to have a shower. When I got back ~45 minutes later, his dorsal fin had colapsed and a hole had appeared near the base, smack in the middle of his fin.
