Thanks. As I was describing above, it had always had a hollow log hiding spot until about 10 days ago. But I think you may be right, I should give him a better and bigger one to see if it makes a difference. It means I won't see the fish but if it will help it feed and grow, it's definitely worth a try.
I offer it far better stuff than fillets - whole or cut fish with all the goodies still in it. Nice and smelly / appetizing feed.
