Vinnie my 10" Midas although still seriously aggressive towards anthing that comes near his tank, and I do mean anything(-He tried to attack the kitchen step when I put next to his tank.) Has mellowed towards me a little. After alot of patience Imanaged to hand feed worms and now when I feed if i leave fingers in the tank he comes and gently rubs his forehed against them. Result!! However if its not feeding time then he still hates my guts.
