Let me chime in on this one. I currently have a green carpet in a 20H, stupid newbe mistake as to the size, but i've kept him for almost a year and he isn't slowing down. I got him at about 6" across and now when he expands, he's close to 14 to 16" tip to tip. Beautiful specimen, I must say.
Now for the bad news. i have kept him well fed, but I'm down 2 percs and 1
kole tang. I know the tang is way to small for a 20, but he was seriously only in for a week to clean up the last of some hair algae and he was back to the LFS. He went into the tank at about 1.5". Please no flames, it was the last resort.
With this said. I was going to move it into a 46bow with some clowns thinking that territory may had played into his habits.
Are you going to Dirks on Saturday? If you want him, let'sake up a deal at Dirks and you can pick him up on your way home.
