I have 3 Powder Blue Gourami, 4 Orange Platies, 3 Damnation Mollies, 10 Neon Tetras, and 4 Zebra Danios along with 4 snails. The tank is 29 gallons and moderatly planted(working on more plants). One of my Gouramis is hiding a lot. I've had all these fish for around 2 months and this is the first issue I've had since the first week, 4 Mollies died very soon after starting my tank. That Gourami is the only one with an issue. I'm just wondering if it might be stress or what it could be. This is my first tank so I am new to all of this.
