You are able to tame it off of berries and/or meat but the most effective way in my opinion and probably everyone else's is to lure a microbe swarm to the turtle, the turtle will eat the microbe fish or the microbe fish eat something from the turtle, anyways you need to stay near by and protect both the fish and the turtle from salmon, sharks and eels. I hope this helps.

To tame it I recommend trapping it in a behemoth gate cage kinda like a taming pen. Then hit it once then it will agro on to you. Then lead it into the gateway and then close the doors behind it and then. Ik I should’ve said this but. Build pen in shallow water. Then to tame it agro tiny silver wish called microbe fish. There in deeper water. Then lure them in with the the turtle and they will lose agro and the turtle will eat it. BUT it takes an UNGODLY amount of time. Thanks me later 👍

Trying to KO it will just kill it, and trying to passive tame it does nothing as there’s no option to passive tame it

Passive Tame, Eats meat but collects Berry's, difficult to tame.

This things faces looks like a goofy meme for some reason?

To kill get a blood stalker then jump on its back then attack(he/she will not go down because it is Agro at and will swim up).

Dude theres birds arounf my megachelon why

To tame a megachelon (sorry if spelt wrong) in the crystal isles map it isn’t actually a passive tame. Because there are no schools of fish to attract to it so you will have to knock it out and put 300x mejoberries in its inventory maintain it’s torpor this 150x narcotics to be safe

Thank you if you read this and make sure to like it so more people can know this,

You can also breed this on the island

Be careful in the water sometimes for me a Barry will just come from no where and demolish me

I recommend stop listening to the passive tame bs and do the knockout method. All you need is to build three behemoth gateways with only two of them having gates. After words, lure the megachelon into the trap and place the final gateway down. Finally there is two options, you can either lure the megachelon onto land and trap it while using a longneck to its head, or get on its back where it can’t hit you and use electric prods bc they bypass all armor. DO NOT USE CROSSBOWS OR SPEAR GUNS, THE MEGACHELON WILL DIE.

You can use honey to tame it but you need to ghost mode through its shell to see the option.

You can walk on back when submerged

You can also KO tame it, be sure to hit the feet and head, shell does next to no torpor. If you can get on top center of the shell, use an electric prod to deal lots of torpor. Use behemoth gates to trap.

You can knock at out in a trap made of behemoth gates but only use tranq darts or it will die. You can feed it honey after it is KOed

You can knockout tame it with shocking darts and feed it and use gates to trap to avoid wasting time looking for the fish

You will need multiple swarms to tame a 150 on official 1 swarm = 15%

Honey is kibble for them and you can build on them but they're a bit bugged

It’s a passive tame it likes honey

Am I the only one that doesn't like these guys? They get killed easily and aren't very useful in my opinion
