I only have the one male right now and I'll have a 10 gallon I can split up and a 6.5 So I've got the space lol. I want to try my hand at breeding eventually and see if I like it. or if I'm even any good at it for that matter.
I get rubbermaid tubs...3 gallon...and found it works very well. This time, I tried a 2.5 gallon glass, 3/4 full and didn't have any luck with it. The tubs seem to work much better.
I just add a plant, a moss ball for hiding for the female, float an Almond Leaf at the top, and add extract that I make to it. I also found, thunderstorms work well for spawning. I tried two without storms and got no where. They seem to like them :)
After they were a month old, I moved them into a tank, half full..then, I added more water as, now they are going up for air. I found book report plastic (really cheap at walmart for a full pack) are easier than using wrap as, you just clip it on and it keeps the humidity in. The wrap gets all yucky with feedings and I keep having to replace it. The report covers keep the humidity in, but stay in tact.
I also use sponge filters after the first week. I got a turkey baster, added some small air hose tubing to the end, cut in an angle so it skims the bottom of the tub, but doesn't suck up any fish. I remove the dirty bottom into a glass, so I can ensure it didn't pick up any fry.
Just some suggestions I have found helpful with my two spawns, which were my first times breeding. I am all about saving money--I even use clip on lighting with low wattage florescents..they work well for the plants, but aren't too intense..and they are 5.00 at walmart, each. :)
