Once killed use a sickle to get the must Prime Fish Meat.

These guys won't attack you unless you attack them. They will them group up and latch on to you, giving you the bleed effect.

An Ark dev said that these will be tameable in the future!

Tamable using fish baskets from aberration. They seem to flee from the baskets once placed. It is a good strategy to pen then in with fence foundations and walls, or kite them to a pen. Place your basket on the other side of the wall and catch.

I found a 4.5 size and fed it to a 150 Hesperides and it instantly tamed

You can tame them with a fish basket, catch them with fish basket and release in water and it's tamed

If you attack one and don't one shot they will attack you I have noticed they won't if you kill one in one hit they will ignore you.

Place a fish basket to tame this.

Will attack if you attack them, just stay clear of the water in general due to the amount of piranhas that spawn with them

You can tame with basket from aberration then keep in a holding pen for easy on demand prime fish meat

They can be tamed on Aberration by placing a fishing basket in the water, waiting about 30 seconds, and interacting with the basket when relatively close

Even if you only see one, keep an eye out for others after you've killed it.

Think of them as zombie pigmen, don't attack them unless you wanna get swarmed and messed up

Trap them in the shallow water so they cannot go anywhere and just place the bucket on the top of them. Bam. Tamed Sabertooth Salmon

I saw one that made me not believe my eyes.
One that glimmered and shined with colors unique.
I saw one with red scales so bright,
That became every color of the rainbow under the light.
I chased and pursued it, but never caught up.
Until one day I found it again.
And let’s just say,
It lives in the lake inside my base today.

Try not to hit them, because if provoked they suck your blood

Fish Basket only on Aberration.

What do they eat? Need to know when I tame one.

You can tame these by placing an abberation fish trap next to them, and if they stay within a small area for long enough, they will be tamed and transportable with the fish trap by picking it up.

U can get good blueprints when fishing
