How do you seay sorry to a crab

well as the title seays im probly not in the right section but here it goes

A couple days ago i noticed one of my buisy emerald crabs witch never messes with my corals always a good soldier apeared to be nipping at my pipe organ so i i took my deep target feeder and booted him off

last night i seen him messing with my acan lord but i just abserved for a moment he was getting some tiny bubble algae from inbetween the heads so i didnt boot him lator on i caught him by my purple death zoa being realy delicate pulled what appeared to be possibly a nudabranch or some type of worm out from the small colony and scurried off to munch away

now i know there known for nipping at corals but he seems to be verry delicate with them weard but when it comes to bubble algae on a rock he teares into it like a mad man and my lfs live rock seems to always have some on it and when i buy something new i always compliment it with a couple pices of rubble i fugure i try to equal the bioload to me seems like the smart thing to do

now my other emerald crab just hits some junk in the sand if he comes across bubble algae in his endevor some reason he seems lazy he just waits till i pull out some sysis to get active but dont let some gha grow where he can get at it

in the end i guess at this stage im lucky i have 2 cool crabs with a verry cool disposition

 

Each animal is different so it is good that yours like different nuisance algae since they won't be competing as much for food. Don't know how you can say sorry to the crab though outside of not booting it and providing it plenty of food.
