Agreed, definitely a female. Generally if the vent is bigger then the anus it's a female. If the vent is the same size or smaller then the anus it's a male. With how OP's pics look it's definitely a female, also looks like she's either close to laying eggs or that she's just a bit fat atm.I’m trying to learn about proper venting and have been looking at a lot of pics and videos lately, this looks like a female to me.
Lol atleast your one of the few ppl on here that will actually take a fish out of the tank to get a proper vent pic instead of just trying to take a side view pic while it's in the tank like most others do. So much easier to ID with pics like these.Lol.
She just scarfed down a bunch of pellets.
Thanks again for the confirmation.
