Came with a Birdnest Coral from saltwaterfish.com. Good guy or need to flush him?

+1 Trapezia. Nice little bonus, enjoy!

The same way porcelain crabs can give back to LPS and anemones, these guys can give back to acropora. They’ll clean out detritus from between the branches and subsequently they’ll help out wherever your flow falls short- keeping the coral from getting irritated in those tight spots the flow doesn’t do a great job of flushing out.

take what I’m saying with a grain of salt though- I’ve never had one, just read about them.

Nice find (tigrina sub-species). Assure it has a food source (fish foods with meat) or it will find one as it is called a guard crab and will at times feed on coral tissue and mucus and some starfish but keep the coral free of debris also

Thanks everyone! I reunited him with the Birdnest after a dip.
