is your toadstool you bought a yellow fiji leather? Its pretty common but no where near as hardy as the other leathers. Your description seems to fit to a yellow fiji leather, as well as the price. Stealhlr has one as well as me.
Does it look like this?
Medium-high light
Medium-high flow
Dont try to frag the coral
