I started to get these growing on my LR 2 weeks ago. They look like baby frogspawn but I see no skeletal structure to them. Plus I have no frogspawn coral. The tank has been setup and running for over a year. The only change I made was doing 30% water changes every other day for a week with my new RO/DI (I did this because I have a nutrient problem because of the well water I was using which caused the cyano prob I have now)
Any way here is a couple pics. Sorry for the size

Any ideas?

I also have tons of bubbles on the LR since adding MH 4 months ago. They are on only 8hrs/day. Are the bubbles a sign of excess nutrients still in the water?

TIA

First, the bubbles on the rock are normal. They are trapped oxygen from the layer of diatoms and other alga that cover the rocks. Not unexpected, although without enough snails, it will eventually build up into a thicker layer.

As for the creature, its very hard to say. Do you notice if it deflates/inflates at all or is it always the same size? Is it Fiji rock? What other soft or lps corals do you have in your tank? Can you see any openings on the mass... like gaps where water can pass into/out of it like in a sponge?

Wade,

They look to be the same size all the time (never noticed any deflation/inflation). They also do not react when I touch them.
I see no openings in them and no hard structure in them.
This is fiji LR.
Also other inhabitants of tank are some mushrooms, xenia, torch coral, open brain, capnella leather, and SPS.

You dont think its some kind of apstasia right? I have left them alone for now but I would hate to have regret that :?

They aren't aiptasia. I would let 'em grow, they do look a bit like frogspawn.

I'm puttin cash on that being a red algae.

 

[Syris]

Well I'm gonna let em grow and see whats what.

John,

What the heck is a red algae? Cyano :lol: I already have that

I'm puttin my cash with John's.

Hard to tell for sure from the pics, but if they are a nice pink color, then I've seen this before, and it was indeed a red algae.

I found a reference to it in one of my books years ago when it popped up in a friends tank. If I could only remember where I found it.... :?

BTW, it's very cool stuff and can get pretty sizeable. It does look remarkably like a coral.

I have seen many frogspawns. I will have to say that it does look like one. Not any color i have seen but still looks like one to me.
