Bright green thing??

Anyone know what this is? It's almost an inch long, doesn't retract when touched, and almost has a fuzzy rubber feeling to it.

Is it good or bad??

Thanks!

Neomeris annulata (aka Turtleweed). It's a harmless calcareous macroalgae.

 

It almost looks like a sponge when you zoom in the pic. But I haven't yet seen one that green. I'm tagging along to see if anyone gets this one.

 

Wow! That was quick! Great job, Inwall75! I ran a search on google and it's a spot on match when looked up by its scientific name.

Thanks Inwall75! It's a really interesting looking algae, I think I will leave it in there, I kinda like how bright it is

 

I've seen a couple pico tanks full of those. They look really cool in large groups, I say keep them in there!!

 

Yeah it seems to be growing fairly quickly, and there are about 4 of them around my tank. Is this a sign that my tank is almost coral-ready because it a calcareous algae?

It's been set up for just over 3 months now... I'm trying to 'go slow let it grow' (it's torture!) but I'm thinking that I might be ready for something simple, like a frogspawn or some zoas.

 

id say your safe to add some

 

List your parameters for any test kit you have.
Then list your tank size, filtration, lighting, etc. (a lot of people leave this info in their signature so that when we try to help, we already know it)
Finally, list what corals you want.

I suspect that you're like fine for zoanthids right now. You're probably fine for the Frogspawn too but I will wait until you answer the above questions. (Your turtleweed will grow slower once this happens....it now has competition from a calcareous coral that ALSO wants Calcium, Alkalinity, Magnesium, Strontium, etc).
