I've had a betta for about 4 months, and I just got a silver dollar fish. I think my betta may be eating my silver dollar's fins? I'm not sure though. I thought these 2 fish were able to share a tank. what's goin on??
the fins of a silver dollar shouldnt provoke a betta too imensely but it is possible... if you jsut bought the silver dollar and didnt quarantine it it might be diseased... possibly fin rot if it looks like its fins are torn/ frayed
if you had to betta in the aquarium...alone...for a long time...this tank is now the "bettas tank" due to the lack that he is very territorial...he would attack anything you put in there...even if their compatable....I know...its happened to me...twice
