The photo is of a pair of Poeciliopsis gracilis, the porthole livebearer, male right and female left.
We acquired our starting breeders of this species from Rusty Wessel in 2008. Rusty collected the fish from Rio Copan in Honduras. I recently wrote a column about them for Tropical Fish Hobbyist. It’s a nice peaceful little livebearer with a unique color pattern.
The genus Poeciliopsis has 21 valid species found primarily in Mexico. One species, P. occidentalis, the Gila topminnow, is found in Arizona and New Mexico. It’s endangered and can’t be collected. That’s a shame since the males are red and black.

Do you sell these ( portholes) ?
Yes, we sell Poeciliopsis gracilis, the porthole livebearer. Please go to http://goliadfarms.com/shop/poeciliopsis-gracilis/. We should post a photo soon.
I’m not sure how your comment got lost, but it did. Yes, we still have this fish.
I haven’t seen these guys show up on your shop listing yet. Are you still working on them? I’m keen on ordering some from you!
We were just down to breeders, but they are due for processing. We’ll do so tomorrow (1/28/15) and I’ll let you know if we are putting them up for sale.
Hi, Charles – are you still working with these fish? I have a small group left I think are from the same collection, and I want to pick up some others to reduce bottlenecking. Also – any trouble w sex ratios?
40 to 50 is quite alot butit depends on how many gaonlls the tank is there are manyyy 4 foot tanks. there is a 50 a 55 a 75 a 90 and a 120 in a 50 i would stay with about 10 to 15 and the same in a 55. in a 75 mabey 25 to 30 and in a 90 about 30 to 35 and i have a 120 and i haveabout 50 or more in it and they are doing great and they breed like crazy.
