fins spliting?(discus)

  • We are currently upgrading MFK. thanks! -neo
if you look at the tipsthey are split. now maybe this is normal but only 2 out of 8 have it. the one in the pic was like that when i got them but the other one just started. so what causes it? i have others from the same breeder that are a little older and they dont have it.
