lol I was mostly kidding about the constipation XD That's great you have room! Yay! So yeah, definitely look into the breeder box for her to make sure that most of the fry live, otherwise both of them will gobble the fry up before you can even begin to count them!
I have a mesh breeder box. Will that be sufficient? I was planing to just let nature take its course since the tank is packed with plants but I am kinda doubting it now.. I really want a couple to survive.
Oh yeah a mesh one will be fine. That's what I kept my fry in for about a month, granted I only had 5. And then I moved them to my 5.5 when they were bigger than my Betta's mouths lol.
Eh, it was just a fry, I'm not particularly sad about it. And actually both the girls I had are long gone, they and the father which was actually their brother are Sunset Wag hybrids. And none have names since I'm not planing on keeping them, once they're old enough and my LFS has room, they're going straight there. But I do call them my little terrors/monsters lol
You could actually sex them right away if you had a magnifying glass and a light lol, same ways as Betta's, look for triangular ovaries behind the stomach and then look at the anal fin. Girls are rounded while boys are sharper and pointier.
But as far as how big, as long as they are bigger than your girl's mouths, they should be good. Remember you have to feed them about 3-5 times a day. I took every flake food I had (including Betta flakes) and crushed them up in a baggie to a fin powder and fed them a tiny pinch about 4 times a day, 3 on days that I forgot lol. But there was a while where I wasn't feeding them adequately enough so they weren't growing very well. But in about 2 weeks of good feeding, they should be big enough. of course it's up to you when you want to release them, they'll still need powdered food for about a month so that's why I left them in the breeder net, it was so much easier to keep track of and they were guaranteed food. Now Rembrandt tries to steal their food from them even if I feed him before I feed them lol
I have my one guppy fry who is just over a month old still in her own tank lol. She was fed egg yolk, crushed betta pellets, brine shrimp, crushed nls flakes 4-5 times a day. Now I feed her mostly crushed flakes and betta pellets. but because I had to make the egg yolk for my sick betta she is eating some of that again. Its a great fry food. i feed her 4 times a day now.. some times more, depends if I am home all day or not. I guess I'll prolly keep any new fry isolated for a while as well for the feeding issue. My adults are sharks and will eat all the food before the fry even have a chance. I only want to keep the females though... what will I do with any males? At what age are males sexually mature and able to impregnate females?
They sexually mature around a month, it's a quick process.
You could certainly put the fry in with the Guppy, although they can interbreed since they are all livebearers, but for feeding purposes, or you could just leave them in the net lol Either way, sounds like you know what to do with your fry after they're born ^^
And you can either set up a different tank for the males until they are old enough to be sold or just give them away to friends, you can advertise it here if you wanted.
I hope there won't be too many males/ it won;t be hard to get rid of them. I don't have any other separate tanks other than the one little Cobra is in. Although, by the time Frigg gives birth, and the new fry are a month old, Cobra should be large enough to go in the main tank. Then I could use her tank for any males or put them in with one of my Bettas.
Also, if you are able to tell males from females early....you could just pet them in with one of your Betta's for a snack if you really wanted to. But of course, that's completely up to you, just throwing it out there :)
