Hi, I added play sand to my tank 2 days ago after being bare-base for about 6 months. The catfish seems happy enough, however the sand is not falling off the body. All the other fish shed the sand within a few hours, they are cichlids and have scales. The giraffe catfish doesn't so maybe its slim coat can't be shed... I'm not sure.
Why has it still got sand stuck to it? Do you think there is a bigger problem with the fish?
