Any idea what this hitchhiker might be? I purchased this Halloween Hermit about 2 months ago and noticed a couple of these barnacle like growths on one end of the shell. I’ve never noticed any movement until last evening. I noticed a black proboscis coming out of the shell! I’ve attached a video and a photo below. The crab changes around shells every couple of days so when he changed out of this one, I removed it from the tank to quarantine just in case pending friend or foe status.
