bugs .....do you know what these are

Question
i look in my tank and there are penny sizes 6 legged bugs in my tank do you know that they are

Answer
Hi Colter;

Are you saying that the bugs in your tank are the size of pennies? That's HUGE! What color are they? Any identifying marks? What kind of fish do you have? How big is your tank?  Do they seem to bother the fish? More details please...
