Monster fish??

  • We are currently upgrading MFK. thanks! -neo
When the channa is large enough it will probably eat the oscar, but if to small the oscar might eat it, bad risk either way.
Fishbase (usually pretty reliable) reports them as maxing out at around 130 cm., and 20 kilos.
They also list them as harmless, which only means that they have not confirmed any report of serious injury or death caused by them.
This is opposed to fish such as the red bellied pacu which is listed as traumatogenic for it's propensity for removing fingers and for causing two known human deaths.
That being said, they are widely spread in an area that the news is often under reported, and the fish is very aggresive in defending it's brood. I have seen bowfins strike boat paddles in similar circumstances, and even the little giribaldi will strike at diver to protect a nest. The snakehead could concievably kill a human if it bit them right. The two people killed by pacu were in New Guinea, using hand seines to remove adult pacu from an aquaculture pond, they were naked and the pacu emasculated them so they died of blood loss and shock. A large channa could easily do the same.
 
I have read an account of a local fishery authority person, not sure of the official title is, being attacked and wounded be a Channa Mircopeltes. I have seen many pictures of fish sliced cleanly in half including a Mystus Wykii. As with most of these type of fish personalities vary, some more aggresive than others. Channa Striata is known to very aggresive, consistantly more so than Micropeltes.

Dorado if not already mentioned is surposed to be right up there as well.

I used to have a 17 inched snake living with a 9 inched tilapia ,, When I first put them in the tank the snakehead tried to bite the tilapia's whole tail:eek: and I thought it would cut it into half but the tilapia managed to escape :nilly: ,the snakes harassed it for about 15 minutes until the snakes maybe realized that they can't eat the tilapias because of its size..They managed to live in harmony but after about 3 days the tilapias started to feel that she's welcomed in the tank so it started to be agressively territorial,It harassed my snakes from time to time..being afraid of tank busting I decided to steam the other one for dinner:D and made a fish fillet and feed it to my snakes

I have kept mine with a Tiger Oscar. I didn't bother about the Oscar being eaten when it was big enough, they lived together. The Snakeheads ( two of them ) at one corner while the Oscar just swimming around.

One morning I woke up to see there was no Oscar, no trace...nothing.

Channa Micropeltes is more aggressive than Channa Striata. Of course personality varies with individuals, but generally this is the case. Striata do not possess teeth like Micropeltes though.

A Giant Snakehead among Snakeheads is like The Great White Shark among Sharks.

Fishbase, talking about Micropeltes being harmless because they have no proof of it attacking people is because they do not know about it. It's not safe to say Harmless like you are sure about it when you are not. ( Fishbase I mean )

You would love the fish, very interractive, aggressive, strong, beautiful ( the difference in Micropeltes is that they vary among their own species very much as in colours, body pattern and the shape of its jaws ) you would enjoy it very much I am sure, I did.

Thank you for sharing those pictures Mercury! beautiful Micropeltes! just love the Torpedo profile. It is one living Torpedo anyway.
 
My I just post here for a moment to say I'm incredibly glad these fish are illegal to own in north america? Our local ecosystems could'nt compete with something like that, and fish and game has poisoned several lakes and river systems when smuggled fish like this got introduced to them. Check your local laws, and never, never release fish into the wild.
 
This thread was about out and out aggressive fish. i have kept Channa Micropeltes before and i have kept fish with them and been fine. the reason people say giants/reds are so aggresicve is because they see it kill a fish in such dramatic fashion using the teeth and action they have and think whoo solitary confinement, but it isn't true. yes they are aggresive but they can be compatible.

Now if we talk about Mystus Wyckii, this is out and out aggresive. it will not tolerate any other fish in the tank and not even your hand most of the time. i have seen it with my own eyes!!! i have about 19 years or of my 19 year life experience fish and my Father has about 30 years worth of experiece with big beautiful and ugly fish.

if there was one bastard f/w fish i would put forward the Mystus Wyckii. no it doesn't have the biggest teeth. no it doesn't have the most dramatic way of killing others. but yes it is in my eyes extremly aggressive.

The most aggressive fish is the africian tiger fish, (the giant) there are two types one a bit smaller. These fish are full of teeth, they make a shoal of piranaha look like guppies. They can reach 6ft plus and will attack anything in the water. They are very hard to come by and are expensive to buy if you can find one. They have been known to have attacked swimmers in africa.
