Emerald Crab -yay or nay?

[Europhyllia]

I don't think 24 hours is enough time for them to feel at home. I see mine all the time. Day and night but mostly night/actinic only. How many did you get anyways? How big too?

2 small females

The only red light I have is a chicken heat lamp...

now you all have me thinking about getting some emeralds.... but i dont have bubble algae. what else do they eat. (dont have any hair algae either) all i have is a little cyano in the sand

Mine always just picked at the rocks like any other crab. Never touched bubble algae that I saw, but what little there was slowly went away.

They eat your tail spot blenny when you're not looking! I thick he may of had ich though. Not sure cause all I saw was bones and intestines. Thought it was a dead bristtleworm at first. I know my loves picking isopods off the glass and pretty much anything not glued down. He never stops picking at rocks and there is plenty of evidence he's eating.

Emeralds are so neato. I love "Mr. Crabs" he's funny little guy.
