8x3x3 Stocking help!

[Nyrkorey]

I currently have 4 xingu bass growing out for my new tank! I plan on doing:
4 xingu bass
Maybe 2 kels
1 type of arowana
2 Florida gar

I want a bottom dweller! I was thinking 2 rays but I don't know if I wanna travel the ray route since I don't know alot about keeping them. But from what I read it's pretty Involved. Unless what im reading is incorrect. Maybe someone can chime in.
Bottom of the tank
2x rays (maybe)
Group of irwini catfish
I love the oxydoras nigar but get way to big most likely.

Again I'm picking one of those im not saying all of them! Or maybe someone has another cool big predator to do? Help would be amazing!

My wife is nagging me too do rays I'm just nervous too screw it up, but all my tanks I have now 1x220 and 3x135s never have any issues at all so maybe I just go for it! What type of rays would you suggest?
Forgot to mention I have a DAT growing out with my bass as well

8x3x3 is great for a pbass tank imo.

Yes I'm excited for them too grow! Them and stingrays will be awesome! I wanna do an arowana too but idk what kind

Might want to consider a giraffe or two for the bottom. They do an xlnt job of keeping the substrate sifted.

I would do a marble not to expensive grow slow and are the most likely to not get to big.
