Usually when you have cloudy eyes its a sign of poor water quality and high nitrates can do this too....however, your husbandry is fine.....other causes are injury, eye flukes, chlorine burns, nutrition, old age.......not really any treatments except for the eye flukes...with eye flukes usually its the pupil that turns/looks white...except for age-the others resolve on their own with some increased water changes and improved nutrition....since the Betta is otherwise acting and eating like its normal self...I would make a couple of 50% water only changes over the next couple of days for now and observe......I only use natural treatment by supporting the immune response....google eye flukes and see if this fits what you are seeing in your Betta...
Thank you to both of you! I don't have a pH test--had it tested once at a pet store and it was "fine" at the time, but I don't remember the specific number. I'll retest it--something odd could always have happened to the water. It isn't any worse this morning and might be a bit better.
I looked at the pictures of the eye fluke and it is possible that it is the early stages of that, but it seems strange that it would appear just the same in both eyes. And it's not the pupil. I also found a similar situation with somebody on here from a year or so ago. He didn't post a follow-up, but I have sent him a message to see if he has more information.
An additional oddity has to do with the details of the search engine here and on some other forums--can't search on "eye" because it is too short and/or common! I found the previous post here through google.
Unfortunately, he's doing worse. Yesterday morning, there was a hint of grayness in his belly. I'm following the steps in Dark Moon's posts for dropsy. I moved him to a QT with epsom salt and I'm also treating him with Maracyn Two. I'm gradually turning up the heat and will increase the concentration of ES today from one teaspoon per gallon to 1.5. After I moved him, I also saw that his pectoral fins are ragged. He has not improved today. I will be surprised--and ecstatic--if he makes it, but the very nice thing is that he is not suffering at the moment. He made a very nice bubble nest in his QT yesterday. I'm afraid that part of today's tasks will be to get ready to euthanize him in case it's necessary. I had goldfish years ago and one developed dropsy and I really have no desire to watch Kenpatchi go through that.
Any treatment suggestions are welcome! About the only thing I can think of to do is to switch to a different medicine. I'll give this one another day and then if he's not better, I'll try a different one.
I've treated Kenpachi with epsom salts and two different antibiotics. I have a reasonable guess as to what is going on. Given that when I tried to find comparable situations all of the threads "dead ended" without saying what the resolution/conclusions were, I wanted to post what I THINK is happening. In Kenpachi's case, the white spots on the eyes are identical. Also, looking from above, you can really tell that they are just on the cornea--they aren't something inside his eye. Because of that, I think they were caused by a build up of pressure. Also, he started to develop dropsy. My guess it that the dropsy has not progressed much because of the epsom salts rather than the antibiotics. I suspect that all of this was caused by organ failure. What caused the organ failure in the first place is unknown. The water parameters were perfect when I tested them, but who knows. I will say that he is from Petsmart, sort of like getting a puppy mill dog.... However, I also don't dismiss the possibility that I introduced something to the water by accident that was toxic. In any case, there are no signs of parasites. When the dropsy seemed to be getting a little worse, I upped the epsom salt to two teaspoons per gallon and that seemed to help. I think he's comparable to a hospital patient on palliative care at the moment. He's still eating well and swimming around, but he's losing his color. As long as he seems comfortable, I'll continue as I am. When he's not eating well or having trouble swimming, I'll euthanize him.
While I am not happy about the situation, I at least don't have that frantic feeling of "if I could only figure out what to do I could save him!" The irony is that I now basically have a betta in a bowl!! I don't want to put him back in his tank because I can't count on it being a stable environment at this point. He has a "betta log" to rest in and I'll pick him up a fabric plant. I feel like I'm taking care of somebody in a rest home!
