thanks, he's on catfish pellets at the moment, he seems a bit indifferent though. I'm going to get him some frozen prawns and bloodworms and see how he goes. I guess I need to thoroughly defrost the food first, is a microwave ok for this?
BTW the gills are a much deeper colour now, since I got him in a tank of 20 degrees, the shop I bought him from had the temp at 28 degrees, he has also passed a fair amount of gravel. ouch!!
