Can anyone help?? TQ

Located in Costa Rica and Nicaragua. Males gets to around 1.5 inches and females around 2 inches in size. They are slender specimens with orange gray hue body, black dorsals with translucent orange in the center. The males gonopodium are fixed off centered on the body, and it has a hook at the end, to keep it inside the females when mating. And yes as the scientific name literally means Strange Hooked P*nis. I find it funny every time lol.

Located in southern U.S (South Carolina, Georgia, Florida, & Louisiana), they are the smallest Livebearers in North America, with males reaching 0.8 inch in size, and females 1.2 inches in size. Weirdly enough, this species has one of the highest body size to gonopodium length ratio. They are olive gray in color with black vertical lines going across the body, and a black dorsal speck.

This is my oldest male liberty molly. Its between him and his brother(who is almost as impressive physically but nowhere near as impressive color wise) who fathered my hybrids. The footage looks a bit funny because i had to take it from far away, if i get close to the tank they’ll hide.

Located in Cricamola River, Panama. They’re named after the river where they’re mostly found. Males reaches around 1.2 inches and females 2 inches in size. They are olive gray in color, slender body, blue eyes, with yellow around the iris, yellow fins, and having a faded reticulation between the scales. Not as attractive as other members in the genus, but being simple they still look amazing.

Located in Cuba. They are a bigger species of gambusia with males reaching around 1.5-2 inches and females 2.5-3 inches in size. They are robust, both sexes have blue gem colored eyes, yellow-gray bodies, and spotted lateral lines. Unlike most other Gambusia species, this species is pretty docile. Also they are a sister species to Gambusia rhizophorae.

She’s putting on size nicely and has a bit of an attitude to her. I finally went ahead and paired my sphenops female with the young sailfin and just decided to add the hybrid female in there with them as well. Im hoping the hybrid fem is gravid for the sailfin but if not she most definitely is for one of her brothers, either way im looking forward to the fry

Limia islai (M) x F1 Tiger Liberty (F) - (75% islai, 25% salvatoris)

Welll night time tank sweep and one of the Tiger Liberty females left me a surprise tonight. Too bad it’s the only one so far. I’ll check on the tank in morning for more. I’m playing it safe and put that fry with my endler fry bc of how tiny it is. It was super stressed out from me catching it but it has stripes. Not sure how well it’s expressed yet, but I’ll give it a week to get its colors. Proof Limia x Molly can make fertile hybrids past F1. This made me very happy to reach F2. Let alone using a female hybrid with unknown odds on fertility. I still have no clue which female dropped it and if all the current F1 females are fertile or not or have reduce fertility, just this one fry for her first batch it’s possible it’s reduce fertility. Now I’m confident their brothers are fertile so I should get F2 backcross to Liberty soon.

Update on one of my 2 male Latipinna X Salvatoris hybrids. I am highly impressed with their growth speed and vigor. I have one female from this same batch who is currently gravid for a young male latipinna of mine, im aiming for a cool water resistant sailfin like molly with the energy and vitality of the salvatoris.
Funny enough ive been at this project for a while now and in the past 3yrs i have yet to successfully raise a batch of latipinna while on the other hand ive had the Salvatoris about 1.5yrs and im on my 3rd generation. The latipinna grow slowly, are weak against parasites and changing water parameters, and they tend to waste away whenever they are moved from tank to tank. Ho

First off, this is a longish post so be ready to do some reading.

So I’ve come to you my fellow fish nerds with a question. Several months ago I came into my possession 20 or so baby fish. The fry were maybe an 1/8 of an inch long. I got them for about $2. Currently I’ve got 8 to 10 of them still surviving and doing well in my 75 gallon tank. They live in a mixed community with tetras, killifish, and cichlids.
My question is, what are they? I know they’re some sort of livebearer and I think they’re platy’s but their body shape is too elongated compared to what I’m used to. I actually got some regular platys and when I see them swimming next to each other, the regular platys are stockier and about the same length. I’m not sure if these guys are platys, mollies, some sort of hybrid or possibly something else entirely.
Anyone got any ideas?

Are these fish worth selling? Endler's Livebearer (Poecilia wingei).
I have some baby guppies. Females are silver male father has blue and snake skin pattern. Nano.

Located in Andros Island, Abaco, Bahamas. Sister species to Gambusia manni. Also close relative to G. nicaraguensis. Hubbsi (males) evolved to have longer, bony gonopodium tips, because of the presence of predators, they mate via forceful thrusting instead of courting. Males gets to around 1.3 inches, and females around 2 inches in size. Appearance wise they are identical to Gambusia manni, with their olive gray bodies, short yellow dorsals, black vertical streak going across the eyes, tiny row of pigment spots on the fins, but unlike Manni which has short gonopodiums, they sport a longer gonopodium.

His dorsal has gotten so bright since I upgraded his diet. Plus I have a handful of fry he sired with his colorless brother. I’m fairly confident his kids should throw some nice colored males.
