Hi, I have a betta fish who has been happily living in a 10 gallon by himself with decor and all the things he needs for about 6 months now. Heater set to 78, his filter is an Aqueon 3 gallon but the other filters have all been too strong for his fins, he is a Dumbo Ear. Now he has a strange bump on his eye, pictures bellow. His other eye is normal. He has been acting perfectly fine otherwise.. interested in food, swimming around, etc I recently was dealing with a lot of algae so I used some AlgaeFix a little bit ago, but I've since stopped. I just did a 50% water change yesterday and a 25% today. I usually add Prime and Stresscoat to the water change. These are my parameters as of yesterday. Nitrate - 10 Nitrite - 0 Hardness - 75 Chlorine - 0 Alkalinity - 50? pH - 7 Ammonia - 0.5 Please help my little baby, idk what to do. I'm considering picking up Melafix and/or some Pimafix tomorrow... would that be a good idea?
