In mobile, they are not rideable but you can tame them easily but there is a lot of other anglers,plesiosaurs and other deep creatures. If you want to tame one of them, you need biotoxin on your hotbar. You can easily find them everywhere in the end of the water, you just have to dive in. And today I mated 2 of them and now I have a mutated baby electrophorus xD(I have no idea what to do with it).Thanks for reading!
