i have a 20 gallon tank. fully cycled.
my current stockibg is
6 white molly
6 golden amd black panda molly
and 6 more schooling fish whose breed i do not know
they all are doing well and good eating well and there is no agtession or deaths whatsoever.
i want to ask that can panda molly amd white molly breed??
i have a batch of fry of 32 now 28 of theem are what seem to be white molly but rest are more like black and golden. my black and golden mollies are not pregnant at all they are totally normal. the fry current are in a breeder box in the 20 gallon tank i am feeding them crushed powdered pellets. we dont have any brine shrimps in my area so please dont blame me amd amazon does not sell it.
i need advice about the fries as well if they cross breed and how long to keep fries away from others. it been 12 days since i had them but everyday i find 2 or 3 more fries so the batch gets an add up every now and then.
hope you read it fully amd respond

The two types of molly you have in your aquarium are the same species, just different color morphs, and they will interbreed. I would also consider getting brine shrimp eggs to hatch on your own in order to have a higher survival rate for your fry. The large brineshrimp are too big. I personally as a breeder don't like crossing color morphs because your putting mut fish into the cycle, but you can do it if you want. And sometimes you can get stable color variations by doing this. Just a heads up also even though it isn't a big deal, your mollys aren't schooling fish as stated above, but rather shoaling fish.

Both of them are mollies, so yeah, they can breed. A lot of livebearers also interbreed too.
They can only do that if they have similar ancestors. Molly and guppy can cross but offspring are infertile. Platy and swordtail can cross (most strains in pet stores are a result of this). But molly cannot cross with platy or swordtail. The ancestors and shape of gonopodium are the ways they have to match up to be able to cross.
