I went to Walmart today and saw some ghost shrimp for 26 cents a piece. I know it's probably not smart to buy fish at walmart but oh well. I also got a mickey mouse platy that is yellow. When the guy put them both in the same bag the ghost shrimp attacked the platy and bit part of it's tail off!!!!!!! I got four shrimp. I was wondering if they could go in a tank with gouramis, mollies, and platys? right now I have them in a 6 gallon tank with a male guppy. Oh and what do they eat?!?! I know nothing about shrimp. Thanks for the info!
