I don't know if I'm just being a worry-wort or if there is something going on with him.
What size is your tank?
What temperature is your tank?
81.4-84 (I'm struggling against a house that's regularly getting up to about 86-88F. I'm doing everything I can to try to cool his tank down. On chilly nights the heater keeps it at about 80.5)
Does your tank have a filter?
Yes, though it's as baffled as I can get it.
Does your tank have an air stone or other type of aeration?
Is your tank heated?
What tank mates does your betta fish live with?
What type of food do you feed your betta fish?
Omega One pellets, NLS pellets, with frozen brine shrimp and bloodworms as supplemental treats.
How often do you feed your betta fish? Twice a day.
How often do you perform a water change?
I try to do it once a week.
What percentage of the water do you change when you perform a water change?
I aim for about 50%
What type of additives do you add to the water when you perform a water change?
Prime. Lately, I've been adding some CO2 Booster to try to increase plant growth, and today added a 1/4 dose of Flourish Comprehensive.
Have you tested your water? If so, what are the following parameters?
I test my water parameters at least once a day, sometimes more. The spreadsheet of results can be viewed here
. The tank in question is the second tab. Chloramines keep my tap water at .25-.5ppm ammonia, so if my water tests in that range I tend to add Prime to detoxify it, rather than stress him out with additional water changes. Adittionally, the nitrates in my tap went up recently, so water changes won't bring those down.
Symptoms and Treatment
How has your betta fish's appearance changed?
It looks like his eyes are swollen. I'll add pictures at the bottom of the post.
How has your betta fish's behavior changed?
Sometimes it seems like he has a hard time seeing things.
When did you start noticing the symptoms?
A few days ago.
Have you started treating your fish?
If so, how? I've only added one IAL. Otherwise, I've been doing my best to keep his waters clean and warm-but-not-too-warm.
Does your fish have any history of being ill?
He nipped his fins at first, until I added IAL and more plants. Monday he somehow hurt himself and lost a few scales, but those have grown back. (I was out of the house when he hurt himself, so I don't know how.)
How old is your fish (approximately)?
I purchased him as an adult from Petco maybe a month ago.
And I'm sorry, I can't get good pictures of his eyes. These are the best I can get.
