thats what the guy at the fish shop told me too. he said a guy turned up with a bucket with 200 odd fighters in it coz he was going overseas and needed to sell them. he said he had them all together , that he had 400 together lots of males in there, that he spawned a few females at same time adn when the babies were a few weeks old, he put them all together and he had no problems, i think he had plants and things like those boats you can get for tanks for them to hide in.
we are going to try it. i have some fry that are 2 weeks old and going into a tank later this week. i have put 3 pairs together tonight. will i be able to put them all together, even though there will 2 1/2 week gap??
i guess as long as your tank is large enough its fine.
