I just lost a young presumably female festivum that had a prolapsed anus/vent and now I notice that I have a female bolivian ram with the same condition. They both appeared fine in every other way, but the festivum perished within a few weeks and I fear the ram is heading down the same path. Is this caused by a parasite? bacteria? virus? Is there a viable treatment and if not is this condition contagious...because if it is then 6 other rams a couple cutteri and cory cats have all been exposed. The festivum used to be in this tank till I put them in their own 75. I need help!
