why arnt they eating ahhhh!!!!!

iv had them for a week and they seem not to be eating any of the algea waffers i am giving them tell me y

Could be one of several things. Firstly, you have only had them a week. They are shy creatures as it can take them a long time to settle in. Secondl, they are nocternal, when they are put into a new tank they revert back to their nightly ways. so they may be eating but not while you can see them. Finally, they are algae eaters, so they may be quietly working their way throught the slime and algae in the tank and have no need for the wafers yet. I'm sure theyare perfectly fine as long as they were introduced properly. just give them some time to settle in
