Can they live without the acro? I want one, but just have lil frags.

They are cool but I’d really be interested on how much they benefit the sticks.

I wouldn't think so. I never see them anywhere near my frags. Even wider branch colonies (like some thin branch stags) they dont seem to care about. They like the ones with tight branchs and protective hiding spots. I'm not 100% sure its a requirement though, I just dont think a frag is going to keep it comfortable. (Unless of course those frags are multibranch and more akin to mini colonies.)

The colony where the Cymo crab resides:

Great pics! That cymo is cool looking but I have had a ton of those and never found one that color and never found one that doesn’t eat or bother the coral. Most of the time they have blue or white eyes and just a grey hairy body, sometimes it’s barely hairy at all and sometimes are hard to tell apart from some of the others if they are small enough. I end up pulling any of the cymo crabs off the corals just because they are hard to find later on.
The larger ones can do damage where they sit if they move from their non acro corals onto an acro but if it’s big enough can do fine.

Does he live away from the acro colonies?

The last picture shows he cant even fit in some lol but that brown/red in the back he can (barely) but there is a tiny crab that spends most of it time there. I never see them fight but id image the little one has the claim since its so easy for him to hide out.

I have a large staghorn in there as well, but i think the branches are just too far apart for the big guy to get comfortable.

A good excuse for me to go buy some more coral colonies lol
