My Betta, Cosmo, started out with cloudy eye that went away with Tetracycline. Since then, he has lost his lower fin, starting at the base near his body and it was rotting away. I tried the Tetracycline treatment for another round thinking this will help. It did not.
I have since gone through SEVERAL different treatments with no results.
I have tried each of these treatments through their durations -Fungus Guard, Life Guard, Maroxy, and Bettafix. I have now started Maracyn and
added some aquarium salt and Stress Coat.
Now his lower fin is gone and you can see his fin bones, he has now developed a white patch near his tail that looks like he is losing scales and chunks of his body and it keeps getting bigger. When I do water changes I see debris from him like he is sloughing off his skin. He eats well (except today) and now stays at the bottom of his tank. Any ideas what else to try? I thought with the spectrum of drugs I have tried that I got any bacterial, fungal, and parasitic infections....but he continues to get worse.
I have moved him from his regular 3.5 gallon tank to a one gallon bowl, and change his water every other day.
I have been treating him since April 2!
Size / Volume of Tank: 3.5
Water levels are normal
My aquarium contains: Just him, gravel, betta log, betta leaf hammock, 3 fake plants.
How often do you perform water changes? now, every other day
What percentage do you change? 100
How often do you clean or rinse the filter? don't use a filter, it seemed to stress him out.
What water conditioners, medications, or products do you add to your tank on a regular basis? I always use Top Fin Betta Water Conditioner
BEFORE - with lower fin intact
Yesterday - no lower fin and white spot eating away at his body
