encrusting macro ID

[greenighs]

Can't find an ID for his anywhere. Any ideas?

whoa... that's what Swamp Thing's brain is made out of ><

cool looking stuff, hopefully it's not a bad algae.

 

[greenighs]

No ideas, anyone?

Clare,

I have no idea. That is very interesting! Is it just a fluid-filled sack like Valonia? How fast does it grow? Where did you get it from?

No, it's fleshy, like a cactus flower. Not growing very well, alas. I got from my local fish store, I'll have to find out where it was collected from.

Clare,

I recently read through The Modern Coral Reef Aquarium Volume 1. What you have looks very much like a species of Codium they list.

HTH,
Kevin

I agree

 

[greenighs]

Thank you! Good to have an ID. It's not doing so well, though, and has thinned out quite a bit since that pic.

I'm sorry greenighs,

What kind of lighting is it under and how far from the lighting is it? Is your water very clean (low nitrates and low phosphates)?

Clare,

I just saw this page and thought of your algae. Could what you have be Dictyosphaeria?

Dictyosphaeria is listed about 1/3 of the way down this page:

I had some of the growing on a piece of rock that my hermits and snails couldnt get (against glass) and as soon as I moved the rock they ate it in one day. It was like they were all waiting for the rock to be accessable. Its a shame, it was a cool algae...
