Rock nems are pretty tough - they can get by with the least amount of light of the nems (I believe). It will not host those clowns however
. Feed it Krill once a week or so to start off; as it gets healthier and adjusts you will have to adjust as well. I've found they do fine on light alone.
Is your clown goby in the photo, I can't see it. I feel I should warn you. I had a very small one, it got sucked through the slits of the over flow. If yours is very small, I would cover it with screen.
hm... really? well the lfs said they dont feed them because they sell to quickly.. so maybe thats why he devoured the silverside. but i will.. try in another few days to see if he eats.. maybe go with a smaller piece.
