Blue sponge, blue mandarin, blue starfish

what has your success been with the blue sponge? Feeding water current?

This is nut_hatch I'm just on a different account. Just got the blue sponge a few days ago ,but I have successfully owned yellow and red sponges for about a year. I feed my tank daily for the fish and for the sponges I feed New Life Spectrun reef micro-feeder 2-3 times weekly . As for current the blue one is sitting in front of a power head. The other ones are placed in medium flow around the tank and if they accumulate to much sediment I move them to a higher current and brush them off. Hope it helps!
