He is 10" now. I know this to be correct because I moved him in a 10" net and he filled it up. I tried putting him in the 240, but the Dats just kept pestering him so he went back to the 40B after a day. I have always been a firm believer in giving my fish one day off a week from food. That was yesterday. Today he splashed almost 2" of water out of the tank. I thought I had a leak at first. He was just all jumpy and splashy from hunger. I fed him more food this evening then he has ever had in one sitting. Calmed him right down. He basically did his own mid week water change. It looks like that plan won't work for me anymore. When he get to 2+ feet it could be a problem. He is going into a new 150 in a few days. As of right now he will be the only mid-top water fish in the tank. It will hold all of my polys and the giraffes cat. If I remember I will get a picture when I move him. Plan on seeing missing scales. Today a lot went flying.
