Fishing Nets (Farm-Like) + New Mob Ideas

Imagine with me. You place a net down, night falls. In the morning, there are 3-4 fish in it. You get XP from collecting fish. It should only have 2-5 slots of inventory so that players have a harder time making hacked farms. Some code that takes down production if another net is within 10 blocks. Mobs could break them, and you have to repair them in an anvil. Maybe new mobs like frogs and tadpoles can be caught in them. Maybe new fish variants! I have said maybe a lot! Some new items like net wire. Craftable with string and... More String? Adding bait could increase production, or it could be like a furnace. I've thought about this a lot!
