isopods I.D. (and Sphaeromatid pics)

most of these are reef safe but there is types that can
cling onto and kill fish over time.they can only be seen with
the lights off and the best way to tell if you have the bloodsucking
kind is to put a yellow tang in the tank as they stand out more
on the side of the tang.there is a few good sites out there with
pages of info on them and how to get rid of them.
usually new tanks will have population explosions within the first few months
but this should calm down,if not you can add fish that will feed on them.
have seen problems with them annoying zoa's, they dont eat them but
crawl round them which can force them to stay closed too much which
then starves the zoa of the light and food it needs.

good post m8
