I have had bettas for 10 yrs., each lasting 3 yrs. My yr. old guy is not happy. I recently bought a new water conditioner and I think that might be the probem.
After changing the water, it soon appears cloudy, with a floating "oil like" substance on top, and looks gelatinous the next day. He is sluggish now but still eating.
Here are some particulars that I have always done.
I change the complete 1 gal. bowl water every week with "conditioned" week old water.
We have reverse osmosis water so I was advised to do this. I recall using a few drops into a gallon container that I cure for a week before using, however, the new conditioner instructs to use 2 capfuls to a gallon! Seems like a lot. The brand is: Bettaplus by Nutrafin.
My bowl is cleaned with thorough rinsings, however, I do have glass stones at the bottom. I just shake and rinse out any old food or wastes, then refill with the water. As I mentioned, I have been doing this for many years and not had a problem until my fish reached "old age".
Should I change conditioners? Should I boil the glass stones to be sure they are clean? I also have a "fake" plant, but that is thoroughly cleaned weekly.
HELP!!! I'm watching Skye become very inactive. He is either lying at the bottom or hanging on top of the water. His usual water bubbles are very few and I fear he isn't getting enough oxygen.
Also, should I have a cover on top of his bowl? I have had one, but took it off because of my latter concerns.
Thank you for reading my OCD worries..........
