Anyone know anything about sea sponge?

[Canadbis]

I have cut pieces off of my sponges when I first got them. to stop the death from spreading, It does work, be sure to get all of it. Dont worry about having small sponges for a bit they will grow.
I feed my tank phyto and reefroids and haven't had any problems with my sponges...yet.
My orange branching one seems to be growing quite well.

Good luck

You know what is really weird? I had purple sponges grow in (lots of little pockets of them) on live rock that we had out of the water for a good hour while we drove it across Calgary. We have had it since we got our tank up and running in November.

I had a die-off of livestock that I blamed on water quality. If the sponge and corals made it - must have been a different issue?

I think the "volunteer" type sponges are much hardier than the ones that are collected and sold in LFS. As BigAls BC said, they're collected at depth and probably aren't adapted to any type of exposure to air or changes in environment. The types of sponges you have found in your tank might be found intertidally in the wild where the surrounding environment changes on a daily basis. Or it just might be one tough mutha

It is a lot more than one. There is one big patch and then several - probably more than twenty - little patches on one rock. I bought this rock from a Calgary reefer who had it in his tank for over a year, but he did not have any sponges on there when I bought it from him(?)

Saltwater is so strange and cool!

You probably have the right conditions for their growth and maybe he didn't. I know when I switched tanks a couple of years ago, many of the rocks were bound together with a white sponge that I had never seen in the tank before (it was only between the rocks) and I haven't seen it since. Currently I have little bits of yellow, some different white and some purply blue sponges in my tank. Pretty neat.
