Please help me ID these metallic/orange egg sac looking things

Hello all! I was hoping someone could help me to identify these small orange egg sac looking things on my live rock. there is one cluster of three and another single piece an inch or so away.

They are metallic in appearance, with slight hint of fluorescent orange. They look very neat. However they remind me in shape/size what spider eggs look like.

I thought maybe they could even be tiny fluorescent orange mushrooms popping up (although i keep none of this variety in my tank). however they are more rounded or bulbous in appearance.

A very neat aspect of marine reef keeping is the beautiful, random things that grow and develop uninvited in a marine aquarium (in my opinion).

I hope i was descriptive enough and maybe these photos will help.

thank you

I think that is red bubble algae. I have not dealt with it, but as far as I know it's "invasive" and people say you want to get rid of it as soon as possible. They say not to brake it because if it's sexually mature it will spread spores all over your tank. I also hear emerald crabs will eat it.

 

thanks damon,
I have been looking it up with google and it does indeed look similar.
It seems as though a safe way to remove a small amount of it is with a flat head screwdriver and to remove the piece of the rock it is on...

if this is bubble algea does anyone know of an easier method???

thank you.

 

emerald crab or water changes, I've had the green type off and on in my tanks and sorta like it, but I've never had it really grow. I've had hydroids make me brake down a tank, so I know things can get bad, but I've keep emerald crabs in most of my tanks and just do an extra water change when I see them and they just go away in my experience.

 

This is what I do, I just grab twist. Turn of pumps and they all sink to the bottom and syphon them out, easy as pie.

I think both the red and green are attractive algaes, and I always have a few hanging around.

 

Thanks Corailline,

So in your opinion would you say that the 2 small pathes ( a trio and a single) are something i should just leave alone for now. ????
Yes, they are very attractive


Also, Damon, i am just ifffy about adding any more snappers into my tank. but if push comes to shove i will try it.

I do 10% water changes every other friday. I try to keep it regimental :

thank you all for your help. It is appreciated very much

 

What are you worried about the emerald getting at? they have always been very peacefull in my experience, but I feed a lot so I'm sure they where always very full.

 

If you like them personally I would just let them be for now. If all other algaes are in check they should not get out of control quickly. New tanks might have a problem with this and if that is the case I really liked my emerald crabs, they always kept it in check.

I have like 3 small patches that I never do anything to, they never get any bigger.

 

@ Damon,
I guess i just assumed emerald crabs could become aggressive (??)

but i guess thats what an assumption without research gets me, right!?

You never have any trouble with your crabs? how many emerald crabs do you have in what size tank???

thank you for your help

 

I was always told to be cautious with any crab a they are omnivores and become opportunistic feeders. I guys if they are small you wouldn't have much to worry about but they aren't always ready to remove either...I'm struggling with 3 hitchhikers right now...
