I too wondered about them, specifically their rep, I know the basics, but as stated by TBTB I've never read anything bad other than feeding behaviors being aggressive and setting them off to eat or attempt to eat a tankmate. What's their reputation like that is claimed to be so bad? Personally I'd treat them like a larger bolt or blochii, or most medium sized cats. Semi-aggressive, more predatory, and larger, but tankmates and water conditions etc would be similar. And do they have the potential to reach 2'? I think biggest pictured I'd seen was 20" though I haven't really done any digging or research on vulture cats...
