I think I have doomed my poor betta. Last week we left out of town for a weekend trip and just prior to leaving I made a change to the intake lily pipe on my bettas aquarium. It broke so in a bind I dug through my box of spare parts and rigged a temporary solution. When we get back two days later I check on the fish and he has lost some of his color. It also appears the stupid cat was up on the counter and managed to get a paw in there possibly because the lid is askew. I cannot be 100% certain though.
He was fine the first day, a little lethargic and not his usual self but he was eating and swimming around. I did a partial water change on day two, he was swimming around less but still eating. I did a full test of the water and everything was fine. All the parameters were excellent so there was nothing leading me to believe it was elevated levels causing this so we continued thinking he was stressed from us being gone for two days or worse the interaction with the cat. As the days roll by he is less and less active, barely eating and the last three days he has been either resting on a plant near the surface or just hovering at the surface taking labored and frequent breaths.
I finally had to go into panic mode yesteday and stripped the tank. Today, same deal.. floating at the surface, upright taking frequent breaths.. color is mostly washed out and gone, he was a beautiful purple and now splotchy light color. He is not interested in food although he did eat yesterday. I am at wits end and don't know what to do next. As much as I hate the thought of it I am contemplating putting him out of his misery because watching him sit there only makes me think of him suffering. :( Not sure where to go from here other than put him down.
