Hi, i just got a new plakat betta yesterday and noticed something I havent seen in another fish before...
Hes perfectly healthy and I think its potentially a birth defect,
but he has whay looks like two mouths? One on top of the other.
The first is a double mouth which is quite big... And he breathes from it. The other one is permanent open and part of the bigger mouth, which is what he uses to eat food with.
Is this normal...?
He definitely has no sign of anything else... And I am quite sure he's 100% healthy.
