i have a fairly new tank only been up for a month, i seen a tiny starfish after i got my tank set up and everything a few days later i noticed another one then a few days another one now i have just seen yet one more.. i have 5 tiny starfish now.. i know its not the same one in different places b/c i see them sometimes all at the same time on their different rocks and the one i found today is on the glass.. they are a light brown color and 2 of them have 6 legs and the one i found today has 7.. i seen a decent size white one but he only had 3 legs and i only seen him one time.. i wanna get a butterfly but the one i want says it may eat my starfish so i guess ill hold off on getting him.. does anyone else have these little guys all over ? i think its neat that they just show up like that.. find new stuff in my tank all the time and ive only had it up a month!
