I am working on putting together a 75 gal all male peacock/hap tank. Currently, I have 2 male and 2 female ruby reds growing out in a 29 gal tank. They are each about 2 to 2 1/2 inches. Would the 29 gal tank be big enough to leave the two females and one male in it as a breeding tank? Ideally, I would like to add a third female to this group. They would be that tank's only inhabitants. If the 29 gal is to small, what would be the smallest tank I could use to house a breeding trio?

If you have a male that isn't too aggressive, one male and three females might work out in the 29 gallon. I've certainly seen it work before, but then make sure the females that aren't breeding have plenty of places to hide when the other two are. As your sig says though, it doesn't always work, particularly if it is a more aggressive male.

I would recommend a 40 breeder (36 x 18) as a good starting point. I have tried 29s and I always ended up with beat up females.
