If you fish these with sap/leech blood, you can get alot of things. Fish, leech blood, metal, iron ingots, angler gel, hide, keratin, rare flowers and mushrooms, obsidian, prime meat and fish, silica perils, organic polymers, then plenty more! Fishing will be something you want to do. I recommend alot of rods premade, get a seprate base just for sap collection, andddd ofc a raft full of chairs.
Unlike the other creatures in the game, this fish here is actually meant to resemble a variety of different species and subspecies. This is why they come in a huge variety of colors and sizes. Also the bigger fish do give more meat, and may give more prime fish when killed by the correct creature. They can sometimes cause lag due to how many of them spawn, these tasty fish spawn in the hundreds
Personally, I just want to be able to catch the small ones and raise them in a pond structure like Koi but who knows. Great way to get EXP if you’ve got a wide hitting tame like a spino! - Survivor Belle
