Hmm, they have been in there since I moved the tank, they don't seem to be very pesty for me....yet lol...but I will be sure to deal with em on the move. The big one is kinda cool looking(if it is a majono) but he is different from the smaller ones quite abit, but still has the bumpy appearance in a way. (they are on small rocks of their own so I will just get rid of the rocks)
Thanks for the info, it's good to know, I have just been letting them chill cause I didn't really know what they were and they didn't seem to bother anything, my goby sits in the middle of the smaller ones all the time and just chills.
