What are these strange things in my tank?

[NedFlounders]

1. There are at least 3 of these tube things. They don't move, sway, or drift. They appear kind of hard like a shell...



2. These little green "pearl" looking things only reside in this spot in my tank. Tucked tightly into this little cranny...



3. This black, soft, tentacle thing. Seems to be a sponge of some sort? And it also is growing in another location...

First look like somme soird of an algae to me but im not sure.It could also be a vermetid snail .Second is bubble algae.Dont break the bubbles or try to scratch it in aquarium because it will release spores and contaminate the whoole aquarium.Last i think its a sponge.

If you cloud the water up. Does the thing in Pic 1 release like a string of snot? If so it's a vertimid Snails....just chisel it off with a screw driver those guys almost took over my tank and am still battling them....

Pic 2 definitely bubble algae.
As 2Smokes said. Remove the rock and carefully remove the bubbles. If you pop any just make sure to give the rock a really good rinse in saltwater before adding it back to the tank.

Pic 3 does it move if you touch it?
If not probably some type of encrusting sponge.

Do you have tweezers to grab #1? It almost looks like a small piece of chaeto (macro algae) from the pic. Not going to hurt anything if that's the case. A lot of people like to grow this for nutrient export purposes in their sumps, fuges, or a reactor.

As the other two have said #2 is definitely bubble algae. Don't break in tank. You actually might be able to pull them off without breaking them (but try this out of water).

#3 is probably a sponge. It's fine to leave alone.

Thanks everyone. The thing in pic 1 is hard like a piece of macaroni. Definitely not chaeto unless it's petrified

For the bubble algae, could I suck it out with a pump of some sort?

And pic 3 seems spongy to me as well. It appears soft and parts of it sway in the current.

Managed to get some slightly better pics. Vermetid Snails? If so, they are popping up all over the tank.

That last picture definitely looks like vermetid snails.

Yep I agree definitely vertimid Snails. Take the rocks out. Chisel off with screwdriver they pop off pretty easily just make sure you get it all. Rinse good in saltwater. That's what I have been doing....got 4 more to deal with that I can see started with 18-20
