Hey i had a few questions the first is i have a few of these little critters that look almost like shrimp. really small maybe 1/4" long are they a sand crab? will they hurt anything? Also i have a bunch of these round red/maroon bubble looking things growing off one piece of my live rock. Any ideas?
