The Emerald Crab has been great at controlling algae in my tank. It eats Bubble algae regularly and helps keep the water clean. I noticed it occasionally nibbling on small fry, so I’ve separated them now. Overall, a useful addition to my reef setup.

I added this crab to manage algae growth. It’s active and eats a lot of green algae. I’ve seen it scavenge on leftover fish food. It’s not aggressive, but I keep a close eye on small fish to avoid any issues.
