Live rock thingamajig

[MeghannWB]

Can someone please help me identify these things? I’m new to the salt water aquarium and am just starting this ten gallon nano. I have some experience with freshwater but I am aware that they are very different. This is some live rock I got and it has some fun things on it that I can’t seem to id on Google? Oh, and don’t mind the peppermint shrimp that photo bombed my picture!

Coral skeleton not alive.

All three of them? One looks kind of like some kind of barnicle

Third image looks like a sponge. The rest are just skeletons unfortunately.

Is it in that last pic I can't tell with that one. A barnacle will open and close and has these feathery things it feeds with does it move at all? If it's a sponge you should be able to squish it a bit with your finger.  Most of the time it has some give not like a skeleton.

The squishy thing helped a ton!! None of them a squishy at all so you were right Lazyfish, they are all skeletons unfortunately. The do add character to the rock. I can’t imag how beautiful the would have been alive if they are this pretty dead!! The barnical one doesn’t move from what I have seen but it’s most likely another dead coral seeing as that is what the other two are. Thank you both for your help. I have never been part of a forum that is so quick to assist! I appreciate that

Meg,

 

Welcome to reefing.  Most of us are addicted.  Sometimes you will hear opposite viewpoints.  I have been a reefer for 45 years and I often press on things to see if the are  hard or squishy.  

 

I suggest you start a tank journal to keep all notes and the progression of your tank as it matures.  There is a forum specifically for this.  You can expect a progression of differrent algae as your tank cycles.  It helps to know this in advance so as not to try and fight the natural  cycle as tank matures.

 

have fun.
