I just got a small frag of birds nest and found out it had 3 crabs in it which i know 2 of the 3 are called acro crabs pink with black mask and one is dark in color but looks like it filters the water with feather like mouth.. and a snall snail as seen in the pic below.

Plus i dont know the type of this bird nest .. and if the white tips and coloration is normal or not ? This is my first sps

That looks like some sort of deep water acro. Is that a possibility?

Not a birdsnest. Huge score with the crabs!!

look up porcelain crabs or anemone crabs. sound like one.
