Serpae Tetra

[Jebus]

i finally caught my two serpaes nipping my male betta's fins
i was wondering, since females have smaller fins, will the serpaes still nip at them?
thanks

I've always found Serpaes to be nippy with long fins. I don't have long finned fish now, so no problem really. A larger group also helps to divert their attention.
