In The Sims 4 base game, you can catch Kissing Gourami in the rivers of Willow Creek and Oasis Springs. The best spots to catch Kissing Gourami are the Desert Bloom Park from Oasis Spring and the Magnolia Blossom Park from Willow Creek.
Kissing Gourami is a fish that typically lives in rivers. With enough patience and high enough Fishing skill, you can catch this fish in any river.
Make sure to level up your Sim’s Fishing skill to increase the likelihood of catching rare fish. After reaching Level 5 of the Fishing skill, your Sim will be able to catch Kissing Gourami quite frequently.
The best approach is to work on leveling up your Sim’s Fishing skill and then focus on catching specific fish.
To quickly boost your Sim’s Fishing skill, you can ask other Sims to mentor you. While being mentored by a master fisherman, your Sim will fish like a pro. This increases the likelihood of catching rare fish.
By the way, after reaching Level 8 of the Fishing skill, your Sim will be able to spot sparking fishing signs. These shiny fishing signs indicate your Sim can catch rare fish in the area.
Just like all fish, Kissing Gourami will spoil after 24 hours. Put your fish in a fish tank or in the refrigerator to keep them fresh for longer.
Happy Simming!
