Most lawnmower blennies won't eat a prepared food. Is there areas in the tank for him to hide? Unfortunately, this is one of those fish that need an established tank, rather it be QT
or main. Maybe you could pick, up another piece of LR
for the QT
, algae seems to grow better in areas of natural sunlight so placing the QT
near a window to get direct sunlight may help get some film algae started. So long as he's strong enough to hold out til the algae gets started. You may have to consider adding him to your main tank and hope he's not carrying something.
