As a Christmas present, my mom placed an online order for invertebrates and macroalgae for my tank. One of the things she ordered is a red sponge (which I have been wanting for quite some time). Now that it's close to arrival, I was wondering how to acclimate it properly to my tank. I know they can't ever be exposed to air, so how should I go about acclimating and introducing it into my tank? Thanks!
