It's difficult to keep them well fed. They need a large established system...even if you can ween them on cyclopeeze or mysis, it may not be enough. This fish is also very suceptible to harassment, especially by pseudochromis, wrasses, and actual blennies. The scooter "blenny" is actually a dragonet, so it will not graze on algae...it feasts on pods, and needs lots of them to survive.
