so i got some fish today for my new tank and i was looking in there and all of a sudden I saw this little white clearish thingy moving around! it was a shrimp. she must of scooped him up when getting the fish. now..i dont know exactly what kind it was or anything. what do they do in there? what do they eat? i dont want him to just..die! i might have to call the store but i dont want to do all that stuff really. it will be hassle trying to get him and taking him to the store b/c the store is not close to where I live. any suggestions
