Just though this was cool, recently got some female emerald crabs from reef cleaners in hopes of tackling a moderate BA outbreak (even though nitro is undetectable) , they have completely ignored the Bubble Algae …
One of the emerald crabs kept going to an area in the rocks and eating some sort of detritus , the area where one of my fish hangs out , and the fish wasn’t happy with said emerald crab so kept poking at him causing him to run back down the rocks
Fast forward to the next day and the emerald crab is now using a rock flower as a hat/cover so he can feast on the rocks without being disturbed
