Challenging ID!

Looks like some type of sponge to me, pic is not that clear.

 

poke it poke it!! jk. its got to be a sponge. if you cant remove it, it has grown on to the rock... like a sponge.

 

i like how you point it out with a heart... really lol that is super funny

 

I'm starting to think it may be a sponge. I never knew they could be "feathery" and furry. I have a bunch in my tank, but they don't look at all like this. Hmm..I'm still not convinced....but I'm leaning towards sponge!

 

Lol, well, yeah...

 

whats the texture

 

It is soft and fuzzy. It looks like a feather boa (see earlier post of pink boa), except growing upwards, like a plant. It's also at the top of the tank growing in direct light (usually sponges like dimly light areas, I thought?).

 

some sponges are partially photosynthetic so they actually like light

I doubt it's sponge from your description though.

 

I know. It's so weird! I want to know what this is!! Lol I've been searching the web like crazy, and I can't find anything like it.

 

idk.. there are some crazy looking sponges out there. but i didnt think about the lighting so now im second guessing what i said. this might be weird but maybe its a sponge with algae growing on it...???
i like my poke test... use a stick... if you dont think its a sponge i would relieve it of its... command??? is it a new tank or an old tank??
