Hello Again to everyone. I have asked a lot of questions lately and you all have been great. For so long I thought I was a professional, until know. With my first smaller non-aggressive tank things are different and I am a newbie again. I have a 20G tall with 6 tiger barbs, 1 Chinese Algae Eater, and 1 Raphael Catfish. I purchased the Raphael Catfish a month ago and I never see him eat. I know that they are nocturnal and I know that some people don't see them for months. Last night was a rare sighting of him sitting there in between my strawberry rock for an hour. Whether it's flakes, algae pellets, or catfish pellets he just looks at them. Is he eating?? Is how they are, feeding off leftovers when I am sleeping? Any advice from people that have owned a Raphael catfish is much appreciated. I am upgrading to a 90G in a while but that's another story.
