Hey guys,
wondering if I could please help getting some ID on the crabs, The filter feeding crabs have spread like wildfire. I have seem at least 7 new tiny ones perched atop the rocks. The bigger ones tend to stay hidden a bit more.

That top one, with the dark claws looks a bit like a gorilla crab to me. Bad news. Might want to try and get it out, though someone might know a bit better than me.

Filter feeding crabs look like anemone/porcelain crabs. Those are harmless but would appreciate a mixture of fine particulate food (reef roids, phyto, zooplankton, cloudy supernate from thawing frozen food).
Thanks for the feedback. I have noticed how they come out when I feed the fine grained/crushed food for the baby mollies, and as you say the pieces of cloudy water from the Eels shrimp/meaty food.

Yeah they filter feed but they will also readily snatch up mysis if available.
