Wow!! He looks huge in that tank! I did the conversion, like a 111 gallon tank or something?! Nice! Gotta love bow fronts! Make measurements practically impossible unless you remove the fish!
Hmm I wonder if one of those would do well with a black ghost knife, they require like 120 gallons, but that's my dream fish, and after looking yours up, those two would look awesome in a tank together IMO!
