Which one is the bigger killer, Hoplias Aimara or Channa Micropeltes

  • We are currently upgrading MFK. thanks! -neo
Ah didn't find that picture floating around yet. But coming from my personal experience having both of these fish, it is really an aimaras aggression that would take the win on a 1v1. That being said, I think I had a 40cm Mala dropped into a pond with 3 60cm channa micropeltes and 3 70-75 alligator gars that ended up as a big feeder... Even a giant common pleco ended up with only its head.. On top of this all though I think a full grown dorado may quite possibly beat them both out. Mine currently targets my aimaras eyes as soon as they have an confrontation which is why I put a divider up now.
 
Aurantimaculata, about 20 cm in the picture, more like 30 now! (Real pigs!)

wait you actually dropped a 40cm mala in a pond with 60cm micropeltes? And the mala eat them AND 75cm alligator gars? That's hard to believe ...

yeah a dorade could be on top simply because of the speed and brain, but at night .....
 
Yes you misunderstood me.. The Mala was the one that was the goner. The 40cm Mala was stocky and thick, thought it would be ok with the rest of the monsters. I usually dump a kilo of feeders every 2 weeks or so. Lol
 
Ah ok yeah that makes a lot more sense. Well guess it could be either one of the other pondmates since either micro and gars are quite aggressive.
 
From my experience between the two species I am highly more inclined to believe that it was the micropeltes who did it. Gars usually just eat what they fit in their mouth. I've seen the micros tear up large fish that I buy from the wet market.
 
Well sadly still no answer from the owner of the dead giant aimara about how big his new one is. So far we know there are claims of 88lbs aimara and micropeltes of roughly the same weight. Anything proven did not pass the 40lbs barrier and both species seem to be pretty close.

Yet there are two other big species in the channa tree which are rumored to get quite big, channa argus and channa marulius. The info is even more vague there, but considering both are reportet to grow quite a bit longer than both aimara/micrpeltes, they might also be heavier in the end.

In case of marulius, there is a video of fish which reached over 40" in lenght:

 
Length only means longer not larger. Reticulated pythons are the longest snake, but green anacondas are the largest weighing much more. This fish, looks old, and not very thick bodied. So while it may rival the aimara and micro in length, I don't think it does in weight.
 
Yeah i agree, the heaviest documentet aimara was 17kg at a lenght of 114. These two marulius at the same lenght would not come close to that weight. But if marulius and/or argus can truly reach 180cm, they will be heavier, even while beeing not as thick in built, since they are not that much slimmer (like an eel). But this is big if, because as you state, these two look rather old. But since the marulius genus is very widespread and thow two might have been kept in a small tank very long (not unusual in japan), we dont know.
