Soooo i keep a close eye on my water chemistry....i sold my mexican turbos back....got some other snails....now my corals aint getting messed with.....i thought..... then one morning i see that my crab...i think....has shoved my ricordia off the live rock and into the crushed coral....well i cant have that so ireached in and gently picked up my little friend and put him back where he belonged and gave my crab a darn good scolding he abruptly flipped me the claw and moved along up under some rock or whatever....anyways my ricordia is covered now with brown crap and seems to be melting into detrious...has my little friend been murdered...did i cause it....is it all over or what do i do?
