My 20yr old son has a female betta with classic dropsy signs. I have api fin cure (doxycycline hyclate) and api super ick cure (malachite green and nitrofurazone) on hand. It's late and no stores are open and I am just arriving to this situation. Will either of these help? I have aquarium salt, Epsom salt, heaters, katappa leaf, prime. Ideas? Parameters good. 0 ammonia 0 nitrite. None of the above (except heater) is currently in the tank.
