I would pick up a good book on them. Most sponges are considered hard to keep due to strict lighting and feeding requirments. Many fish pick on sponges as well so you need to make sure the fish you pick are not eaters of sponge. Easiest way is to determine what type of sponge you like, then see if you can really have it. I have a piece of Tree Sponge in my tank and so far so good. I have 380 watts of vho lighting in a 70 gallon and my tank has been established for 6 months or so and was seeded with some great LS from another store. I also maintain very good water quality (water changes weekly) and suppliment with DT's Phytoplankton for my entire tank. I don't know everything about sponge, but mine is still alive :)

Also don't let air hit a sponge, this is almost always fatal. White or black spots appear on a sponge can indicate death- assuming white and black aren't the natrual colors.
Some sponges need silicates to grow, which can also cause diatoms.
Usually the brighter the sponge, the more toxic it is should it die.
