Mono peacock or Ansorgii bichir?

[Caveden]

Both bass and bichir cost $80 respectively. I can’t decide which to choose. I would really want the peacock bass, it looks amazing and a price that is awesome as well. However the issue I’m debating is my arowana. My aro is about 13” and this bass is 14”.
Previously my arowana killed my kelberi peacock bass that was about 7-8”. Now this peacock bass is about twice the size, and I heard monos are more aggressive. So can this peacock bass defend against my arowana? Or should I stick to the safer option and just get a 16” ansorgii bichir instead?

What size tank would either be going in?
What are your tap water perimeters? (hardness, pH, conductivity)?
What kind of circulation (pumpage in gph) does the tank run?

6 x 2.5 x 2.3 ft

6.5pH, I have kept peacock bass and am keeping bichirs in those parameters now, so it’s fine

I have no clueabout circulation, I can however adjust the pump age of the tank. It’s a sump tank if that’s what you’re asking? Sorry I’m unsure what that means.

I was wondering if it could be suitable for the addition of the bass mixing with my arowana. Previously I kept my old peacock bass only 7” with my arowana and it didn’t end well. However if I add in a peacock bass larger than my arowana, the peacock bass will be fine right? If not I’ll just go with the ansorgii bichir.

Cause this time I have the choice of a bass 2x the size of my previous bass

Sounds like good water parameters for either.
Tank size good.
P-bass usually live in a waters with strong directioinal/laminar flow, and high oxygen content.
Bichirs often live in low flow areas like oxbows (same as an arowana), and can easily handle low oxygen waters.
These were the crux of my questions.
If you had said high pH, high mineral content water, I would have leaned toward the bichir.
If the tank was much smaller, I'd go with the bichir.
If the current/flow in the tank was slow, say less than 1,000 gph, with only canister type filters I would have also said go with the bichir.

I can adjust the oxygen levels in the tank as well, same as the flow of the tank. Are you saying I should go with the peacock bass though since the criteria of my tank meet that?
my arowana killed my previous bass. However this time the new peacock bass being sold is twice the size of the previous bass. It would be fine right?

Tysm Duane’s. This detailed explanation made me learn more about what parameters The different species of fish live in.

I will forever vote Bichir.

 

[Caveden]

I do want another top dweller though. If Duane’s says my parameters are fine for either one, I’m leaning more towards the bass. I’ll continue deciding

Bichir… peacock bass are time and again trouble makers for me. Big or small.
