Hay guys i found these guys on a iceberg near the blue obellisk stuck inside easy kill hope this helps

They Spawn Mainly At Herbivore Island, UpVote People Need To *Sea*

U can trap the leedsicthys by using a couple on stone gateframes and lead it with a raft then when it eats the raft (before or after) u just slam the final gateframe(s) and there u go, a trapped leedsichys (make sure u arent the only one doing this and also if it despawns, do it again)

Well i just got raided by a fish..

Captain Ahab would be the only one mighty enough to tame the alpha leed. MOBY DICK!
