Actually I'm not
trying to breed them, I don't really have the room to raise many! Its a pretty heavily planted tank, pH near 7.5, temp around 78. I had two males and two females but the one female died about a month ago. Unfortunately she gashed her side on something and I couldn't get the infection under control
They're all probably pushing 4 years old. Strangely enough, the female I have is a bit odd looking and I think she's a mutt or mutant, in any case she never breeds.
I do have 5 that I raised from this summer, but they all ended up males (they're in a second tank). I have 3 more that are from the fall that haven't colored out yet but I'm guessing they're female (finger crossed).
Like I said, the splendida are easy to get eggs from all the time even when I don't try. Given infinite aquarium space I'd probably raise some herbies and lacustris, but I don't have room at the moment.
