Net a Fish Rarest Fish: Demi-Gods and Catching Tips

Which Rare Fish Should You Chase?

Your Net a Fish rarest fish hunt has a standout target: the Celestial Mantis, a Demi-God catch. Valuable fish earn money in your showcase, so landing one can help fund your next round of fishing upgrades.

Keep these catches on your radar as you build your collection:

Catch	Rarity
Jellyfish	Mythic
Great Hammerhead Shark	Apex
Celestial Mantis	Demi-God

Use the cooler’s rarity and odds sorting to compare your catches before selling anything. Check the fish’s displayed income, too: your collection goals and your next showcase upgrade deserve separate decisions.

Keep the Celestial Mantis on your hunting list, but put valuable catches to work along the way. A Mythic Jellyfish or Apex Great Hammerhead Shark can contribute to your pool while you continue fishing.

Fuse Duplicates Before Selling Your Stacks

Duplicate fish have a purpose beyond immediate cash. The cooler’s fusion ladder starts with these requirements:

• 10 fish → Shiny
• 8 Shiny → Gold

Check your stacks before selling duplicates. Keep enough for a fusion when that upgrade fits your collection or showcase plans.

Auto Fuse costs 199 Robux and handles fusion whenever a stack reaches the required amount, continuing up the ladder. Choose it for convenience if you want the cooler to process eligible stacks automatically.

Review your auto-sell settings whenever you change collection goals. Keep the fish you want to collect or fuse out of the selected selling range.

Turn Your Catches Into Showcase Income

Your pool earns cash every second from showcased fish. Compare each new catch’s income with the fish already occupying your slots, then place the stronger earners.

For showcase-focused upgrades:

• Extra Showcase: 299 Robux for three additional slots.
• 2x Money: 399 Robux to double money from showcased fish.
• Auto Collect: 49 Robux to collect showcase earnings automatically.

Pets hatch from Ocean & Abyss Crates and hunt fish for you. The +1 Pet Slot pass costs 399 Robux and lets you have two pets out at once. Both pets hunt fish, and the second pet’s money bonus adds to the first pet’s bonus.

Prioritize occupied showcase slots before buying additional space. When a valuable catch is sitting in your cooler, compare it with your current lineup and give it a slot if it improves your income.
