The Rummy fish are a type to feel more comfortable in groups. the breeding is not quite easy, and the average fry is about 2 - 3 per hatching. I put in lots of different plants they love to hide in them. I change 10 percent of water per week with a chlorine cut, and I feed the bloodworms mixed with their regular food. I keep their filter at about 20 percent dirty give or take 5.
