Q&A for How to Fish in Terraria

If you mean pre-hard mode, there are various crates. A wooden crate, for example, will drop apprentice bait, journeyman bait, coins, various potions, pre-hard mode ore/bar, sailfish boots, tsunami in a bottle, extractinator, aglet, umbrella, climbing claws, Guide to Plant Fiber Cordage, and radar.

You need to go fishing in Forest with 1000+ Water Tiles.

Follow the instructions provided in the article. The instructions are equally applicable to the mobile version.

Yes, but you must be in hardmode, and have the Truffle Worm in your inventory.

You can't catch an arapaima. They are an enemy, not a fish.

You have a chance to catch crates every time you fish. If you do get a crate, hold it until hard mode so the stuff you get will be more useful.

The Golden Fishing rod. It's an award from the Angler after finishing 35 quests on PC and Mobile version.

You just have to have them on you while fishing. If you have the baits on you, using a fishing rod will automatically use a bait.

It's a small kind of worm used to summon duke fishron but they are rare to find and very hard to catch, so be sure to be holding on to your bug net!

Worms can be found crawling anywhere. Or, if you have the jump boosts, you can jump and catch butterflies.

You will just need to left click the mouse button.

Swipe down at a medium pace with the attack side of the screen.

They spawn on land in any biome. They are very small, so might be difficult to see, but once you do, catch them with your bug net.

Do it in the same way: Press Y, craft a workbench, make a pole. However, it is harder to get a merchant on Xbox, so get a bug net, grab some bait, go to the ocean and fish!

You just make a fishing rod (see the steps above), then press RT. The end of the line will start moving, then press RT again and if you've done it right, what you bought will be In your inventory.

No. You get the golden fishing rod after completing 35 quests for the angler.

You can do things with them but it depends on what you catch. Some fish can be given to the angler as a quest while others are used in crafting.

If you don't have any fishing pole with higher fishing power than the sitting duck's fishing pole then you can if you want but if you are planning to buy something else, try figure out which one is going to be more useful. Or, you can buy the sitting duck's fishing pole and the item you are also planning to buy. Do remember that the traveling merchant can depart from you, so find him quickly. And if he is selling it, buy it from him. It will be worth it for a while.

Your best bet of getting bait is this: Buy a Bug Net from the merchant once he has moved into your town (Have 50 Silver Coins and he will move in if housing is suitable). Use that bug net to catch Ladybugs, Fireflies, Grasshoppers and Worms. If you have time, use that time to break some rocks in caves that stand on blocks (the rocks aren't blocks themselves but are still breakable with a pickaxe). These, 9 times out of 10, will spawn a worm for you to catch. If you want more bait power, combine a fallen star and a worm to get an enchanted nightcrawler.

If it is blue, it is a Glowing Mushroom Biome. It contains plenty of hostile mobs so be prepared before delving in! The glowing mushrooms can be harvested and used in potion making. Also, the biome, in hard mode, has a rare chance of spawning a Truffle Worm. If you see one, catch it! It will disappear after some time so be quick. Once caught, do not fish with it unless you want to spawn Duke Fishron.
