I have had two Chocolate Gourami's for almost a year now and they have both been very active and seemingly happy. I had them in a 5 gallon with a few scarlet badis, otto cat, honey gouramis, a baby mollie and shrimp. I recently created a planted tank and switched all fish over from the tank except for the (2) chocolate gourami's and the otto cat. since the move my Chocolates have seemed stressed, nothing has changed in the tank except for they have received more room by their tank mates moving out. The waters PH, Nitrate, Nitrites & Hardness have all remained the same since I have had them; they have lots of plants to hid and swim through but also enough free swimming room too move around there is also a very low current in the tank.... the only thing I havent tried is adding peat or almond leaves that some forums seem to suggest... any other ideas to help my little guys out?
