Hi! I was at the aquarium shop yesterday and saw a new batch of blue platys. The guy at the shop said I could have one for free. They were beautiful! I think they are teenagers as they are smaller than the ones I have at home. I have a 30L tank with 9 neon tetras, 1 male mickey platy, 2 female mickey platys, and 1 platy fry. I have lush plants on driftwood and the fishes are quite happy. I would really like to have the blue platys! Would this make the tank too crowded? I do not want the platys to overbreed and do not want to spend too much time maintaining the tank. If I get 1 blue platy, she may look too lonely. If I get two, should I get 1 male & 1 female? I don't want the single blue male to stress out the single blue female. Should I get 2 females? Advice much appreciated, thanks!
