hey everyone. I had my axie for a while now, maybe 4 or 5 months. Only had a little fungi problem which thanks to the advice from the people here I had no problem dealing with. Everything has been fine for about 3 months now until a couple of days ago he or she (named him dude but I am totally unsure of its sex) had his gills pointing forward and was strangely floating around and not eating. I thought it may have been something to do with water movement or pollution (would be strange since I have always had the filter on since I got him and keep testing the water as well) so I turned the filter off and started to change some of the water every day. Now he doesn't have his gills pointing forward anymore and tried to eat but spat the food back out (pellets). and also, I have noticed a funny looking bump on his head. I attached a picture, its not really good but the bumps appears to be sort of red when seen from top and its on the left side of his head (right on the pic). Any ideas to help me ?
