First of all, do you have something to do with the resulting babies? You'll need several live cultures to feed them, a rearing tank, and containers for all the males once they begin to fight. Put the female into the male's tank only after he's made a bubble nest and she's begun to show vertical striping. You'll have to let them see one another for a bit (but keeping them seperated) before they'll be ready to spawn - in most cases. It can take anywhere from an hour to 2 days before they begin to spawn. It's absolutely necessary to have places for the female to hide in the spawning tank, and keep an eye on the two. I've had males who've made their bubble nest, and the female showed striping, but when i put them together, the male tore her to shreds. Remove the female immediatly after they've finished spawning, and leave the male with the eggs. The male will guard the nest and keep the eggs from falling out.
The best setup for spawning and rearing the babies would be a 10 gallon tank with a sponge filter and heater. I don't like to use substrate in the spawning/rearing tank. A breeding net will not be big enough. And you won't want to move newly hatched babies, so you would have to spawn them where you're planning on raising them. I would definatly not attempt it in a breeding net.
OK, Neo. You have a 10 gallon tank, correct? Just this once I'm gonna take the 1 inch=1 gallon rule and run with it:
Red tailed shark: Approx 4-5 inches
Danios=Generally 2 inches a piece, plus need space to swim like mad
Betta=Approx 3 inches
So, you have 16 inches in a 10 gallon tank, tack on a few extra inches for the danios and I'd say about 20. What do you think the general consensus would be about this particular situation?
Veeeeerrrrrry overstocked. Sometimes you just can't have the fish you want and it sucks, no doubt. But you just aren't doing them any favors by making them live like this. I went to the cool LFS in Grand Rapids today, saw 4 different fish I want. Didn't come back with them because I couldn't yet. Trust me, I whined like a baby to the hubby.
Neo,you know I have bettas,and you know i've just bred them. Please go look at the fish breeding section for Bettas. DO NOT but male and female together right away. And DONT take away dad right away either. The info is there. Read a few of my past posts. ITs not hard, if you know what order to do things in.
OK no more fish, until i get a bigger tank, and i wont breed them because i have no room for the offspring, srry i overstocked the tank...begginers mistake, but i will deffinitly hold off on anymore fish until i get my 40 gallon i want
