If you see the stock list for my tank you can tell I have a few fish that need some more mates. In particular I have to mickey mouse platys and three zebra danios. If I add a few red wag tail or some other platys will this be alright or does each species of platy need to be together. Also I think I read that the glo fish are a type of danio. If I added three or four of them with the 3 zebras I already have will that make them happy or do I need to add more zebras? I am trying to add a little color to the tank but I can add more zebras and mickey mouse if that is what is needed.
