Unidentified object on live rock?

Personally I'd keep it. They can release toxins if harassed or when they die, but I think the chance is probably not that great. Plus it's not very big right now, so I think even if it did it might not cause much problem.
It's pretty cool looking and supposed to be beneficial, so seems ok to me.
It's not the one and only. Just the first. The original poster's is the second
How about the pics of the First???
"I've had several inverts that were mainly nocturnal and ALWAYS slept in the exact same spot during the day"
Can you name some of your inverts which displayed such behavior (returning home)?? Never and ever seen any invert, expecially cucumbers, with such behaviors!

I've never had cucumbers.
I had a nocturnal snail that would do it. No idea what kinda snail he was though. He had a sponge growing on him and came in on the live rock. But I didn't even know he was in the tank at first until I saw him one night. He slept in the same spot every day and I thought it was just a sponge growing there because I couldn't see the rest of him lol. I took the pic when he was out in the middle of the night one night, I quickly turned on the light and snapped it. He was actually fairly quick for a snail and would retreat as soon as there was light. I just happened to get lucky because he usually never ventured off the rocks (at least when I saw him) so was hard to get a photo of.
The others were various snails, slugs, etc., not sure of species. Most of my inverts would move around a lot, but some of the nocturnal ones would stay in the same spot each day while they "slept" and would only move at night. I think some nocturnal animals like to pick a specific crevice that feels safe and stay there during the day. Probably an instinct to prevent them from being easily seen/consumed by predators in the daytime.
A lot of cucumbers do tend to be nocturnal, so I'd assume that some species would possibly exhibit similar behavior. But it's just a guess since I actually don't know much about cucumbers in general.
Cool hitchhiker!
I do know of certain fishes which sleeps at same spot most of the time once used to tank/system Rcks/ currents but never noticed such behavior from gastrpods. Their predators are usually stars and/or other gastropods.
Athough imported uncured/cured rocks for many yrs and saved many UFOs and rare specimen, this pic does not ring a bell.
Although not easy to take pics, post more shots from differnt angles if and when possible.
I am curious to what this maybe.
Are you sure it is sponge on its back?
If so, how long did you have this specimen and have you notice any growth of what you assumed to be sponge?
btw RFG, arent you the one who set up plant tank recently.
How did first shipment of algae do in new set up?

I'm fairly certain it was a sponge, but I could be wrong. I posted him on several website and could never get an answer as to what he was, but most people agreed it was a sponge on his back. Not sure if it just HAPPENED to grow there on his shell, or he was actually some kind of symbiotic creature.
I had him for a year and a half or so, and when I took the tank down and gave it to my friend as far as I know he was still alive and coming out periodically a couple years later
. The friend I gave him to is actually a marine biologist and he agreed that it appeared to be a sponge, but had not seen similar. He had trouble IDing what the snail must have been since a shell was not visible and the top half of him was covered.
Actually as far as growth, while I had him I didn't notice any, but when he was moved to my friend's tank the "sponge" seemed to die off somewhat during transfer. It grew back into about the same shape/size it was previously after awhile.
These are the only other shots of him I have uploaded. I will have to look through my hard drive and see if I have more. If I find them I will PM them to you.
Yes I am the one that recently set up a planted tank. Most of the algaes seem to be doing well but my mermaids shot glass seems to have died off (there is still stem left) and not sure if it will come back or not.
I also got some kind of macro (the penny macro from reef cleaners where they send you a random one) but I have no clue what it is. It was really slimy and kinda looks like pieces of light green rotting lettuce. I will have to take a pic. I thought it all died off and decayed, but it appears it just floated around the tank and some has attached to a shell and started growing.
I ended up with a piece of manatee grass on the rock my cactus halimeda came on and it appears to be growing well.
Also got some chaeto in the bags of copepods I ordered to seed the tank and it's started growing well.
Overall I ended up with:
Cactus halimeda
Laurencia
Pencil cap
Flame algae
Red titan algae
Sargassia
Chaeto
Whatever the penny macro was, lol
and that one piece of manatee grass
All are small at the moment, and not much growth yet. I haven't posted pics since I have a brown algae outbreak probably due to cycling, but it is dying down and I'm going to do a water change tonight or tomorrow which should start to kill off the rest. So I will post pics in my thread soon.
It would help if my nerites would do their job and eat some algae, but they appear to me more interested in laying eggs at the moment!
Looking forward to more pics. From what I learned from importing and collecting my own macro was that they were more susceptible to temp and SG difference than coral and fish.
I had greater success when properlyaccliminated just as we do with corals/fish, sometimes even lot longer than fish/corals.
As far as dying/recooperating algae, I learned that by leaving them in the tank, I tend to see new growth from such algae in time, even 6 or more months later.
I collected many algae this summer including turtle/eel grass. I let them be once planted. Althoug they may seem to disintegrate, some tend to start new shoot and/or see new growth thru out tank, even on the glass. Such was observed from previous expereinces. My algae collections now are from temperate zone algae. When brought home, most, but not all, tend to melt away due to warmer tank water regardless of how long I accliminate. I just started to notice new fine shots of turtle/eel grass growing after 6 weeks of intruducing into tank.
btw, you should have some fish to give them much needed NO3/PO4, etc, etc., that is once tank is cycled.
