The ruby emerald crab has been living in my tank for three months and is very active in cleaning algae from the glass and rocks. It doesn’t harm the corals and seems to be thriving. Easy to care for and a great addition to a reef setup.

I bought this crab to help with algae growth, and it has been doing a good job. It’s more colorful than the standard emerald crab, which makes it a nice visual addition. I haven’t seen any issues with compatibility with my existing fish.
