Thanks for the feedback DJ. I don't do all male anymore because it's so difficult to achieve long term harmony and I love breeding behaviour. Having said that, I do keep some LONE male stragglers in my mixed tank and was maybe thinking of a line tret.DJRansome said:Yes. My tret hid except for feeding time and added nothing to the tank. I ended up removing him.
My experiment was all male, so the tret was alone. I would not have tried it with mixed genders in the trets as they have a rep for killing other fish in the tank when spawning. Even each other on occasion.
