I have a 60 gallon planted tank with a dwarf gourami, two opaline gouramis, a veil angel and 6 Von Rio flame tetras. Iāve had the gouramis and the angel for about two and half months without a problem, and the tetras were added 3 weeks ago and have been doing great. Then a week ago, my dwarf gourami suddenly stopped eating. She looks perfectly healthy otherwise, (good color, no lesions, visible parasites, or swelling) and she does swim around from time to time, but mostly hides out near the bottom. All of my water parameters are normal, and Iāve done several small water changes throughout the week to see if it would help. Two days ago, she ate one flake when I fed them in the morning, but nothing since. Then today, one of my opaline gouramis stopped eating. The angel, tetras, and the other opaline seem fine and are eating normally. Iāve been trying to research gourami diseases and figure out whatās going on with them, but I havenāt been able to figure it out. Does anyone have any suggestions?
