seems i have the worse luck with
ICH.. freshwater and salt.. i lost 2 False Percula Clowns, an Royal Gramma, and an Neon Goby to the desease... so my tank has just been roamed by 5 Hermits, a Coral Banded Shrimp, and an young Blenny for about a month... my Q is.. is it possible to just have a Damsel tank? since they seem to be the hardiest

but with the knowledge of them being territorial seems not possible with a 55g long... and ive read that its inverts that make it easy for ICH to break out.. with all this said.. whats the Hardiest fish out there?? and what am i doing wrong??
oh and my tanks been set up for months now and the
live rock hasn't shown its colors.. instead brown algae has tooken over it.. i know i need more hermits but what else can help this problem??
thanx
