All of a sudden my red devil has been acting *very* aggressive and sticking to one corner of the tank. I had always assumed taz was male, but the behavior strikes me as "nest-protection". Is it possible for taz to be female and lay eggs even though "he/she" has never been around another fish?

50/50 that it is female 99% chance that if it is female it is laying eggs even if alone its entire life. Female humans still menstrate if alone in the wilderness their entire lives. (unless medical issues or such occur)
