OK im sorry, I said i had a skimmer but i just dont know what im talking about yet. i dont have any skimmers at all, i was calling my powerheads skimmers..... silly bean. ive decided that im just gonna give it a few days, testing the nitrates and do a hefty water change if my nitrates dont drop.
i noticed some funny little guys on my new piece of rock, i wondered if someone could take a stab at what they are. i noticed little legs poking out of what appeared to be a shell attached to the rock. whatever it is hangs a small thread about 6-7 inches long out of the hole and well i think its fishing. there seems to be a little manhole cover they pull onto the opening when they retreat .
they appear to be some sort of small crab although they never reveal their bodies
