how big should I go?

[Rmacneill]

arowana, clown knife, tigershovelnose,gold datnoid,ornate bichir and maybe some silver dollars or oscars. I been lookin at 120lx36wx30t. but not sure if width is better than depth? 96x48x24 maybe? need some advice please

I would think that 120Lx36w would be better for those fish. The extra 6" of height would probably be beneficial for them too.

 

[Hendre]

120 for sure if you have an aro. Height is good too

Firstly, that's what she said.

secondly, width in my opinion is better for those long bodied fish you have on your list.

That shovelnose will be a nightmare when it gets big. Wouldn't be surprised if it ate your bichir, clown knife or datnoid.

Also the bigger the better always! I would add some black rays

The 120 would work fine, I would rethink the TSN as they become monstrous, as said above Rays would be cool, some peacock bass perhaps?
