I’m pretty sure they make compy noises. I was trying to tame one and I kept hearing a compy, like really close. But it confused me because compys shouldn’t be underwater but nope, it’s an ichthyosaurus.
(I don’t know if it’s a bug or something but it’s kinda funny)
Ummm... so not everyone know this, easiest place to find the fish on The Island map is by going to the vegetarian dino island and searching the shores, it's gonna be dangerous, i will try to get more information on how deep they usually are
Go to herbivore island (The island) at the right bottom. Go to map if unsure. Look around and you should find some itchyosaurus. But be careful, in the water they look like sharks, don’t mistaken them as sharks they have a pointed snout. Like if you found it helpful! :)
In different areas they’ll be different colors so like herbivore island they will sometimes be red and silver or different assortment of the same colors if you find them in different areas they will most likely all have two or one color similar(found one that was gold and blue with a Silver belly and her friends were either gold and different colors or blue and different colors) hope this tip is useful
