We have just got a Siamese Fighting Fish (Betta Splendens) a couple of days ago. I have just noticed that there are a couple of splits in its fins.
Is this normal? I have read in several websites that the fins could have been split by sharp objects in the tank, but I just don't see any in the tank.
Could the fish be stressed? I don't think it's fins are nipped by other fish. We've got a dwarf gourami, which seems to be ok with the fighting fish, and a couple of khulis and a couple of bristlenoses.
