Coral beauty angelfish eating hydroid colony's ?
A few weeks back i bought a coral beauty angelfish. Now previous to this purchase i had tons of hydroid colonies and all my live rock. I found out they were hydroids thanks to another forum member. But i was looking around my tank today and there isn't one hydroid that i can find they all just disappeared! I also have a emerald crab in there is he the one who did it?
