Thanks for the input, the thing is though, I've had females drop fry in my 20g and I've only ever had 1 figure out how to hide well enough that he made it to adulthood. I feed live food about once a week so I think my fish have learned that small swimming things are fair game or something, not sure, either way guppy fry don't tend to survive in my community tank. Also, since I want to try and hybrid the guppies and endlers, i want to be able to keep everyone separated, I want to know who the parents are and see which crosses make the coolest looking babies. That is why I'm wondering whether one of those net breeder things (like this) is a good way to do that, or if I should find a spot for a fry raising tank.
Also....pygmy guppies?! sounds cool!
hmm, that complicates things. i feed live food only a few times a year, and then its brine shrimp which looks nothing like a fish fry.
see, if fry are confined to smaller quaters, they grow much slower. and if they are grouped together, the grow even slower. when i had way too many fry once, i put the female in a breeding cage for a few hours while she was dropping her fry, and then raised them in a 2.5 gallon tank. but they grew much slower then the 4 siblings that were dropped inside the tank and grew up in the 20L. you wont be able to raise 50 fry in a pint of water.
i reccomend keeping the endlers and guppies in your community, and setting up a nano (like 5 gallons) with a small filter with some kind of prefilter so the fry arent sucked in, and putting the females in that after they are really pregnant until they drop their fry. maybe put a breeding trap in there if the female tries eating the fry, so she cant get to the older fry. but id say you can only have 2 batches of fry in there at a time maximum.
yeah, i had an eclipse 6 so i could only keep small fish. so i mixed feeders and fancies, and then selectively sold the largest, drabbest guppies. now they are all tiny and colorful (and come in grey, black-blue, and orange).
took the past 4 years though... but i wasnt really trying, just giving away the bad ones.
