Thank you but I want what's best for him. I am not Monster enough. Let this be a lesson to other monster keepers. Read the stickies and know the adult size of a Silver, over 36 inches. I would be sadder if he busted my tank lid and jumped out and died having only lived a year. He has never killed a tankmate although he has started just recently nipping at the CK's when they eat his shrimp. He has also taken the gars snout in his mouth trying to take the shrimp from him with no harm to the gar. A gentle giant but a giant nevertheless.
