so i woke up this morning and low and behold half of mufasas tail was gone
it was perfect when i changed his water on monday and now its gone. it doesn't look black or clear around the edges, just gone. i have seen him swimming in circles like hes trying to bite his tail, but can he eat his whole tail in one night? does fin rot work that fast? hes in a heated 2.5 gallon and gets 2 100% changes each week.
what is happening and what do i do?
i can seem to post pics but im working on it.
