Well, first things first. His bowl is entirely too small. His fins are frayed due to stress. You need to get him at least a 2.5 gallon home but 5 gallons is recommended as minimum. Filter should be used. If temp stays around 78-80F then you don’t need a heater. I’m not sure about boiling your water. Is there a need for that? It may reduce necessary minerals that the fish need. Get the above items and continue daily water changes for 10 days. Add 1 tablespoon of aquarium salt per each 5 gallons of water on the first day. Be sure to dissolve it in a little tank water before adding to bowl or it will sting the fish. After that, add 1/2 tablespoon of aquarium salt for each 5 gallons of water. See if this makes him feel better. He’s very skinny so feed him more. Several pellets 3 x’s a day. I still don’t see a tumor. Keep us posted.
>He keeps coming up to the surface to breathe(even at night), which was why I removed him from his old 3 gallon tank with the filter and everything. At night he lays on top of the rocks to sleep and breathe from the surface. I could add a plant toy on which he can try and rest or a plastic structure
>>He has an enlarged hump to his side (like dropsy but no protruding scales)
>>>I can use tap water and conditioner. But I'm scared of introducing tap water with bacteria in his weak state
>>>>I have aquarium blue , anti-bacteria and anti-fungus , anti-rot medication , aquarium salt, rennamycin (oxytetracycline fish guy suggested), and fish vitamin to add with food. all of which I have tried on him
>>>>>Should I do a FULL water change everyday or partial change of the 3 gallon tank and should I keep the filter on?
>>>>>> I have kept him in aquarium salt in his small bowl for over a month didnt seem to help , only delay it
I feel that he has swim bladder issues (its like he doesn't even have a swim bladder )paired with numerous other issues , only thing I haven't done is increase his feeding
??? so my main questions are should I do a 3 gallon change everyday, which medicine should I use if I use water conditioner and tap water or boiled water, should I use an aerator ???
