My BGK is my most personable fish, I absolutely love that guy. He usually sleeps in his log, but he can sense when Im near the tank and comes alive, he gets up and starts to wiggle and wag his tail like a dog. Then I'll call him out and he starts coming out slowly, an inch at a time then he comes out and starts darting around the tank looking for food, he scarfs up small carnivore pellets like a vacuum, he just inhales them.
Three years ago he flew out of the tank when he hit a piece of krill on the surface, luckily I was there and I picked him up and put him right back but after that he stayed on the bottom for two years, and still is reluctant to eat off the surface.
Ive had all kinds of fish, but that BGK is something special.
