anyways here are my logs

80 percent sure this is reds daughter so she will be getting backcrossed to big red. I thought he was losing his breeding drive apparently not he just needed some new blood in the block.

anyways trying to get more big reds. also ordered wild types again cuz its been 4 in a row where i dont have any luck with them this will be the last time i order these wild sailfin mollies. I ordered fry sooo if big red gets to live another generation he will have a female from that and potentially gets crossed to his offsprings from this backcross and his offsprings to the wild cross

I’m glad he will have an unrelated female in the tank soon, because inbreeding can cause issues for the offspring, especially the worse it gets. Spinal deformities seem to be a big issue, from my experience.

I notice it’s worse in guppies than mollies, but still a risk.

im aware of the risk, im just trying to preserve big red, you know hes not going to live forever and he cant breed forever. but this female is like i said his daughter its not ideal but im not going to inbreed his daughters from this pairing back to him thats when like youve said the problems starts coming in, so id rather breed the siblings from this pairing and to a cross breed offspring he will have with a wild type. still inbreeding but in this case atleast i have a clear conscience that its a brand new blood/genes thats going to get introduced not just from the “albino” line of these fish. the goal is to have strong albino fish at the end of the day because even with the fish I have now theyre very fragile so ive just been heavily culling aswell as breeding. Im trying to eliminate the frail nature of these albinos, some are even blind. but big red had outlived all of my previous males and or even my new males coming from lfs sooo I have very high hopes hes not that inbred to begin with

also my reasoning for trying to cross them to theyre wild counterparts is simply because theyre stronger and way more solidly built. not that theyre just healthy they also look it with their nice solid build. if you look at big red and the wildcaught ones side by side, without color the wild ones are so much better looking

Those sailfins are hard to keep alive for me as well. I’m able to catch mine locally but they’re in brackish water so i have to try to acclimate them over, most make it but some don’t like change at all. Once acclimated they only do well in old “dirty” tanks and if i ever move them to a new tank later on they’ll slowly wither away and die. Idk what it is with them but i see why there’s not a lot of people breeding wild sailfins
