If I hover my finger over the surface my HM king stares at it intently for a few seconds, jumps, then I give him food because I don't want to just tease him XD Also if I put my hand in the water he comes and sits in it, and he rubs against my fingers sometimes, he sometimes bites my finger lol and of course he also follows my finger : )
It can actually be a little annoying sometimes because I'm trying to change the gravel filters, or put the air tube back in my air stone and he wants to be next to my hand XD I actually have to push him out of the way sometimes, but he comes right back lol
I've had this Betta for two weeks O.O he is really amazing and I love his character XD My other HM king I bought today is very shy and will take much longer to tame.
That's my big boy XD he's so huge, he came right up to the glass
