If a fishing sign is sparking in The Sims 4, this indicates that Sims with a high Fishing skill level can catch rare fish at that location. There’s a very low likelihood of catching seaweed when there are rainbow-colored sparkles around the fishing sign.
Sparking fishing signs will become visible in the game only after your Sim has reached level 8 of the Fishing skill.
If you have Island Living installed, the sparking fishing sign may indicate that a mermaid is using the Aquatic Lure ability. The mermaid blows into a conch shell to attract rarer fish to that area.
As a result, your Sim has a much higher chance of catching rare fish.
⇒ Quick Tip:
Using your special mermaid abilities will deplete your Hydration motive. To recharge your mermaid powers, swim for a few minutes
or get the Forever Fresh reward trait.
Shiny fishing signs can also boost your Sim’s fishing level.
Sims that are fully maxed out in the Fishing skill will catch rare fish more frequently than Sims with a low Fishing skill level.
For example, they’ll catch Angelfish and Pufferfish after three or four tries. In this manner, they can complete their Fish Collection much more quicker.
Conclusion
Locations that have sparkling fishing signs indicate your Sim has a high likelihood of catching rare fish. Use specific bait to increase your chances of catching very rare fish at that location and complete the Fishing aspiration faster.
Happy Simming!
