There's differing opinions in this thread.....lol
"Value" of fish isn't even worth debating.... Its up to the buyer what something is worth. If they think its worth it they pay it. I paid more for "Lucy" then I did either of my Aimara, would do it again in a heartbeat. Best money I ever spent on a fish hands down. Would I spend over $165 for 1" fish that are NOT Aimara? Shoe betcha. lol. CF Panara Lacs. Think I bought at least 5.... Would I do it again? Yup.
Lucy did kill 2 Aimara once they began getting close to her in size. Not sure if this had to do with tank size or not - seems like some fish will fight for a big tank but cohab smaller tanks just fine - maybe space is worth killing for? Lucy always has and is still just fine with smaller wolves. There's an flawless Australis half her size in with her and they even compete for food without issue.
In my experience Lacs are much more curious/inquisistive VS Aimara just straight hating people.... So I would say towards people Aimara are def wayyyy more aggressive. But to tankmates - I'm not sure there
s much difference. I seemed to have really good luck with Aimara and tankmates, but I aquired both mine as small as possible and started them in comm tanks. Raised as "fish" vs raised as mean monsters that are constantly pestered, chased, thier aggression shown off, teased with fingers, fed live etc (probably where most of us probably started out at... lol
