Hi everyone? Hope u all doing well. My yellow lab's mouth, gills and tail getting reddish. I have isolated him and tried salt. No improvement and it stopped eating too. After searching and failing to get medicine from local pet shops, i tried feeding garlic into her mouth directly. Looked like he git little better but the red didnt go away. Yesterday foun "aquadene" anti parasite med in a shop and treated him with that as per the dosage mentioned on the bottle. Today he started eating. Still recovering i think. Anyone know what exactly going on. Because i see another yellow lag getting reddish mouth in the community tank today.
