Is the blue thing in the foreground a sponge?

Looks like one

yes

a blue sponge

not sure if it will do well... low light high current... but i get mixed replies that this needs high high high light top of the tank... I don't know whom to believe ... but i bought it from LFS the guy is very very god... good prices.. $20 for the blue sponge... $15 for true percula... LFS says keep it in a dark place or very low light...
