New female emerald crab and mexican turbo snail!
Update: After 2 weeks with the emerald crab, he has made a huge difference in the tank. All algaes, including bubble algae, and unwanted crap that was stuck on my rocks is all gone. So far she's been pretty peaceful in the tank and doesn't harass any of the corals, I'm really happy with the "female" emerald crab.
I was going to go crab free in this tank as I had a bad experience with a previous "male" emerald crab that quadrupled in size in just a month or two. I'm hoping the 'female" will stay small and peaceful.
