According to Wes, who deals with these fish more than most and keeps them with other fishes, Curus are the most active at seeking other wolves. You didn't need to be rude. I've no experience with the aimara but lately, as more people have been acquiring them and comming them, they haven't been what they're made out to be. And I did say IN MY OPINION. I would never give info on curu off of my experience since I've only had one and I've only had it now for maybe a month give or take a little. And he's been non aggressive. You could be right. But it has size and as the aimara is growing in length it'll grow in overall mass and from my experience, with the multiple malas I've had, wolves do that fairly quickly. But as I said before he has space to play with as well which would play a roll and they most probably won't bother getting into it but I would definitely expect flared gills. I did mention the ray. And as I said lately aimaras are proving all this "hype" on there aggression wrong. As of this year and late last year I've seen more aimaras in comms as the number of people keeping them rises. I apologize if anything I said sounded offensive. And you don't know his specific individual either to say whether or not it would attack another fish that looks similar, which is what Wes said they've done more so than any other wolf he's had. He's very knowledgeable and reliable, I definitely would trust his word.
