clown knife tank

[bouncingbety]

What do you guys think about a 72x18x30 (All Glass 150) for a clown knife? I am planning on using an Eheim 2260 to filter it. I am also planning on keeping my Jack Dempsey (about 5 inches) with it. They are doing good so far.
Opinions please

Clown Knife will grow to large for the dimensions of that tank. Have you looked at any Polypterus species or perhaps the smaller Black Ghost Knife?
