First, make sure no voidwyrms are nearby, as they will try to kill you. Next, pet the Astrodelphis. Finally, put element in the last slot of your hot bar and start feeding it to the Astrodelphis. Thanks for reading my tip!

Tame during purple drop and you will get 100% taming effectiveness like to get this known

U have to pet it and feed element. The amount of element goes up each time u have to feed, but the taming bar will fill up faster. Easy element u can gather by using an anky or pickaxe on the blue crystals in the space between the bridges. In the center of the map

Update: as a baby raising, they eat meat and fish. Not element like it is to tame.

Swim up to the dolphin until it notices you. If it squeaks, you're in business, if you see red sparks from it's blowhole and it screams, you're in trouble. Keep hard element in your final hotbar slot. Dolphins aggro every other dolphin when fed. Make sure the one you want is alone. Always keep the dolphin between you and the direction you want it to go, because it will run away occasionally and you don't want it running into a pack of other dolphins or a wyrm. Sometimes they swim away after 3 pets, 2 pets and a feed, or just one pet. The bite during taming doesn't hurt much so just stay away from the mouth. The bite during true aggro hurts a lot.

Biggest tip: when the dolphin swims away STAY RIGHT ON IT because the taming bar will absolutely plummet 5-10% every second if you don't pet it fast enough. Because of this bring way more element than you'd expect to use. Around 3 stacks of 100 each should be enough. You never know when you'll have to reposition your target or avoid hostiles so be prepared to lose some progress.

Kill all the ones in the pod except the one you want pet it then grapple it with a grappling hook and tame like a crystal wyvern

Space whales now space dolphins? Ark genisis 3 Space fish

Don't grapple it doesn't work if you see anyone say that don't believe it

Increasing dmg stat does not increase saddle weapon dmg. Seemed intuitive based on saddle info but was not the case. Found out after doing more research myself but hopefully I can save someone else some heartache

We’ve got the four biomes, but none of them really suit this creature. Therefore, we can assume that we will be able to go into open space, which begs the question; what other dangers and wonders will we be able to encounter?
