hello! I'm very new to fish keeping and i currently am looking to stock my new ten gallon tank. it is not yet cycled, as it's been set up for less than a week. I ordered a little colorful cave, 6 tall plants, and a pink little castle to put in the tank along with some colorful gravel. so, now is when I need to start thinking about the fish I want to stock my tank with. I absolutely LOVE all the different types of platies, so I was very interested in getting 3 male platies for my tank. (I want to avoid fry) is this okay? will they get aggressive with each other? thanks for the help!
