Most aggressive catfish?

[JESTERX626]

I remember reading about a few aggressive catfish that are really evil in temperament. Are there any super aggressive cats that max out under 20 inches?

Cetopsis and mystus species seem perfect for the bill. Other overtly aggressive fish (read: not predatory--aggressive) are generally larger than 20".

I had a RTC 26" ate about 700$ worth of fish and he also ate a 22" arrow of mine and that was it I got rid of him the next day

 

[necrocanis]

mystus wickii black devil cat, bagarius yarelli, those two have to be way up there on aggression.

Asian red tails are fighters as are wyckii. i had ARTCs that fsquared off with cichlids. The RTCs I dealt with only ate things never fought if they couldn't swallow it they left it alone. The ARTC actually sized up fish bigger or equal to in size lip locked & all with other aggressive cats like marbled. i have seen wyckii fight other fish as well even fish not meant for food.
