I have a 60 gallon planted tank with a dwarf gourami, two opaline gouramis, a veil angel and 6 Von Rio flame tetras. I’ve 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 I’ve 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. I’ve been trying to research gourami diseases and figure out what’s going on with them, but I haven’t been able to figure it out. Does anyone have any suggestions?
