Michael,
you hit the nail on the head. Im only 15 and i do make impulse purchases, but imo lion and goby is just a no no. Common sense? I dont know for sure but Bill, i see you buying and then selling all the time so slow down. One more thing, dont you think that the lion should be in a bigger tank than a 30, keep him in the 55 and put the others in the 30. You could keep your tang in the 55 though.
:D
