great looking wellso. sorry to hear about the blenny. sounds like you could be feeding more. small meals throughout the day are very beneficial. i see you mention nitrates with your current regime, it might help in that regard by not having a single large feeding and instead smaller multiple feedings. will also keep stress andd aggressiveness down between fish, if any present. also, easier to handle bioload wise. if not home, an autofeeder with some quality flakes and pellets and a feeding ring work great to minimize waste and increase fatty fish count.
good luck regardless and thanks for the photo update!
