Anybody know what this finger like coral on the right is? I got it as a "mystery coral"....does it do anything else? ie open up etc
thanks

Isaurus tuberculatus, aka snake polyps. They'll open to feed at night.

I hope it makes it...haven't heard encouraging things...although my green goniopora is doing very well, budding off lots of babies
