What size is your tank? Ten gallons (With gravel and such, eight gallons.).
What temperature is your tank? About seventy-six degrees.
Does your tank have a filter? Yes, but I don't run it all of the time; I've temporarily shut it off until I can make a baffle for it. I've turned it on a few times, but only when I can supervise him with it.
Does your tank have an air stone or other type of aeration? It does have a bubble wand; like the filter, I was concerned that it was too strong. So, I only turn it on periodically for a little while. I'm going to get a gang valve for it today, hoping that will make it a little less strong.
Is your tank heated? Yes.
What tank mates does your betta fish live with? He's the only one in the tank.
What type of food do you feed your betta fish? I've been feeding him flakes, but I'm switching to pellets today.
How often do you feed your betta fish? Once a day; I'm concerned about overfeeding him, since it's so hard to tell with the flakes.
How often do you perform a water change? I've only had him about three or four days. I'm going to perform one once a week.
What percentage of the water do you change when you perform a water change? I'll be changing fifty percent of the water.
What type of additives do you add to the water when you perform a water change? I add BettaSafe water conditioner; it's supposed to "neutraliz[e] harmful chlorine, chloramines and heavy metals in tap water and ad[d] a protective slim coating".
Have you tested your water? If so, what are the following parameters?
Ammonia: I ran out of strips for ammonia; have to get those today, too!
pH: Kind of hard to read... Between 7.2 and 7.8.
Hardness: Closest to 150 ppm.
Alkalinity: Once again, difficult to read... Probably between 120 ppm and 180 ppm...
Symptoms and Treatment
How has your betta fish's appearance changed? He has small "patches" on his face. They're red; I'm not sure if that's just some of his coloring or if it's a symptom of something being wrong...
How has your betta fish's behavior changed? He has began opening his mouth while underwater (not just while getting air). I'm not sure if that's a sign of aggression or not (He did attack one of his plants..). Also, after he gets air from the top, very tiny little bubbles come up.. Does this mean he's losing his air??
When did you start noticing the symptoms? I noticed a little color change yesterday (lighter than the rest of his head). This morning, I noticed that it was red. I just noticed the behavior symptoms today, although I noticed that he would "emit bubbles" when he ate earlier..
Have you started treating your fish? If so, how? No, I have not, as I'm not sure if this is an ailment or something normal...
Does your fish have any history of being ill? Not that I'm aware of, but he's from Walmart.. So, he was kept in pretty bad condition, but not as bad as some of the other fish. He was still fairly active and had nice fins..
How old is your fish (approximately)? I'm not sure.. He's still fairly small.. I'd say anywhere from six months to a year?
