Hermit Crab Shell - Growth on Shell

[LiamR96]

Hello everyone,

First post - looking for some advice/help identifying what this growth is on my hermit crabs shell.

It looks kind of coral like and has grown considerably in the last few days. It appears to move slowly in the current and and has little hairy ends that move and retract as well.

Thanks in advance for any help!

do you have any soft corals in your tank? the last picture vaguely resembles a finger leather

Hi, nothing at all, it’s a fairly new tank only has live rock and CUC at the minute

i'm fairly certain its a soft coral of sorts. i'd wait to see if anyone else chimes in. in the meanwhile, its a good thing you don't have fish or corals. so you can continue to monitor it for growth patterns for a better ID

Thanks for your help, hopefully it is something like that. Will monitor incase it develops into something more sinister
