Hi everyone. I got a question about breeding my gouramis. I would like to try breeding it, but am unsure about the safest mate to choose for it. My tank currently has 2 gouramis in it, one three-spot and one opaline, both female. The opaline is exceptionally larger and more aggressive than the other, as she is probably the dominant female. I would like to buy a male, but don't want to risk any injuries. So should I get a male that is smaller than the opaline, or larger?
At first i thought it should be larger, but I added a large female gourami once, and both of them ended up killing the smallest one. This happened twice, and hence i am in this predicament now, with two instead of the "ideal 3".
Should it be smaller? if so, smaller than which one, the opaline or three-spot?
