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, with frozen brine shrimp and bloodworms as supplemental treats. Just gave him his first NLS pellets, as well.
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, but I've been struggling with low levels of ammonia, so there's been more.
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?
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.
Symptoms and Treatment
How has your betta fish's appearance changed?
There's a small gray patch on his back that looks like missing scales, but I'm not sure.
How has your betta fish's behavior changed?
When did you start noticing the symptoms?
Just now. He was fine when I looked in on him before leaving to run to the pet store to have my water tested by someone else and pick up a couple other things, but when I came home and checked on him, he had this patch. I was gone maybe an hour and a half (had to go to two stores).
Have you started treating your fish?
There's an IAL in his tank, that's all
Does your fish have any history of being ill?
Some tailbiting that seems to have stopped since I added more plants to his tank.
How old is your fish (approximately)?
Adult, but otherwise unknown. I got him from Petco just shy of a few weeks ago.
Here's a picture of the issue.
