Hi, I have a problem with my Ram Cichlid. I will describe step by step this process: 1. I've seen small dots/spots on his head (only on head, symmetrically) 2. On polish forum, users told me that is: Hexamita, so I should raise the temperature (to 30C), and pour medicine (Protosol) 3. After week - nothing 4. I have lower the temperature. 5. After a week - nothing 4. Next three days: Half of Ram's face is black (dark) Fish behaves normally - he doesn't hide, etc. What I should to do now? Cure for Hexamita in a 5 liter aquarium?
