Are These Fish Eggs on My Live Rock

[steve888]

Hello:

My tank is about 4 months old (14G BioCube) and it currently only has four corals in it (2 mushrooms, a torch coral, and some pink zoanthids). I bought a Fiji Blue Devil Damsel over the weekend but returned him/her to my LFS because I felt the tank was too small. Some guides say 10G is okay for this type of fish but others say 30G is preferable. He/she seemed to be very unhappy in the tank banging against the sides and darting all over the place (although I know they're aggressive fish so maybe that was just normal behavior).

Anyway, I've noticed what looks like maybe fish eggs on various parts of my live rock. There are about 12 or so of these bb-sized eggs and I've included two photos (sorry for the quality).

So, if these are eggs what will happen to them since there are no male fish in the tank to fertilize them?

BTW, I'm going to add one or two nanofish to the tank in a few more days...probably two neon blue gobies. Is it possible they'll try to fertilize them if they're male? Am I going to end up with a Fiji Blue Devil Neon Goby Super Aggressive fish of some sort??? :eek1: :eek1: :eek1:

if your talking about those green things thats bubble algea, other than that cant see anything else in your pics that would look like fish eggs

those are bubble algae, you can get an emerald crab to get rid of these guys

The green orb is valonia, bubble algae. I can end up going to plague proportions if left. You can try biological control. I've had luck with emerald (mithrax) crabs. Or, take the rock out and gently pry them off.

Thanks for the Info!

Thanks for the Info!

Wow, not good news but I'm glad to find out what it is. I was going to pick up a Mithrax crab this weekend with my nano fish so hopefully he/she will go after them.

Since I got my corals, I've been running my white lights for 8 hours a day and my blues for 10 hours. I'd like to cut back on that but my LFS says the corals need that much light for photosynthesis.

Anyway, thanks for the quick ID...I really appreciate the help!

just Bubble algae

I had a few spots of this, probably more to come. I've take to taking my frag clippers and getting the rock just below them. If they pop they release spores.
