What Baby Fish Are These? Swordtail/endler?

[crumpybumpy]

Hi--this is the third time I've found these baby fish in my 8 gallon Fluval tank. I am fairly certain they are from my female red swordtail--but she's the only one in the tank-her husband died months ago. But I have 3 endlers in the tank..and one blue endler is a male is is very attached to her quite literally--he is constantly breeding with her. Is it possible for swordtails and endlers to cross breed? I've read on some forums people say yes but many say no. But how could fish of different genus produce offspring? Is it possible?

I also have in my tank a male white molly and female black and white molly---they constantly breed and their babies are little black fish that don't live. I have NEVER seen the white molly and female swordtail mate.

So this time round I have 10 little baby fish--maybe even more---this is a small 8.5 gallon tank. I just bought a breeding floating cage thing and put all the babies in there because the previous ones would live for a week or 2 and then disappear.

So what do you think?

Ive heard livebearers can store the males sperm for up to 8 months.

Yes time scales vary, guppies are usually around 2 months (though some extremes of 4 have been mentioned)

Mollies/platies/sword tails etc. being appreciably much larger, its likely they can store it for longer.

Plus, they do look like sword tail fry

I don't think endlers and any of the larger live bearers can interbreed.

endlers have been known to breed with guppies. Swordtails cannot breed with endlers. That is a swordtail fry. You can expect drops for about 6 months if she was with males in the past.
