i am going to be setting up a second tank thats 30 gallons and i was planning on breeding some platies or mollies for fun and to use as feeders. i want to not be a huge project (as in i dont want to have more then one tank going). this tank will be in my room so i want it to look good as well as have some breeders in there for fun. so i was wondering if there are any other piecefull fish that could go with the platies to add some variety to the tank? also would ghost shrimp be ok to be in this tank or will they eat all the fry? thanks for all the advice.
