What is this?...and how do I keep it alive?

[Brad]

Blue Stuff... not soft, quite brittle to the touch. (sponge?/coral?)

1) Does it like/need light?
2) Does it need feeding of any kind?
3) Does it like/need current?

Sponge for sure.

Light - probably not, though some sponges do require high lighting - most don't.

Filter feeder -- will absorb bacteria & DOC's from the water.

Tons of current.

HTH,

I got a yellow one that looks just like that. Has doubled in size since I got my rocks. 8)

 

[Brad]

doubled in size?

If yours looks similar and seems to be doing well, where in the tank is it situated? Does it get direct light? Strong current? I would like to keep it going as the blue color is very different than most things.

 

[dralarms]

It's midway up in the tank plenty of current around it, and yes it's getting direct light.
