I was given several great looking sponges when I got my live rock from TBSaltwater... They look great in the tank, but I know sponges can be difficult to take care of. Normally I try to do some research before I put something in the tank so I know that I can take care of it, but I wasn't expecting these, so I really know nothing about keeping a sponge healthy. Any suggestions about water flow, lighting, food, etc would be quite helpful.
Thanks much
