I've been perusing this forum to try and figure what to do to help my new fishy friends before posting something to bother you all with. However, I haven't really been able to figure out (even with leafing through all the problems and suggestions here) what's going on with my second betta, Jubei.
When I got him, he was kept in a tiny cup about 1/3 the size of the containers betta are sold in Petsmart, but the pet-store workers seemed very knowledgeable about how to take care of them, and his water looked very clean. The main issue I noticed was that Jubei's dorsal fin was curled, but I thought it was simply because he was cold and in a tiny space. I've had him for almost a week in the smaller 'Betta Cube' that I was able to find at Walmart, and I'm hesitant to move him to the gallon tank I have on standby before I know what's going on with him.
His fin coloring seems to be fading near his body, but the color on his body seems to have gotten better. I haven't seen any fuzziness on his body, signs of bloating, weight loss, or growths, but today I noticed two small holes: one on his tail, and one on his anal fin, both near his body. Plus, there's a 'clear' spot at the front of his anal fin. I've tried putting a mirror and my red VT betta's bowl next to him, and all he's flared is his 'beard,' very rarely. He's been fairly skittish since I got him, but he's perked up a little in the last few days.
After the form, I'll include a couple pictures I took of Jubei in the cup he came in while changing his water today.
What size is your tank? Uhm... half a gallon, if my half-empty jug is any indication. (the Betta Cube didn't tell me how much it holds...)
What temperature is your tank? pretty cold... that's all I know... I haven't found a heater suitable for less than a gallon tank
Does your tank have a filter? no
Does your tank have an air stone or other type of aeration? no
Is your tank heated? no
What tank mates does your betta fish live with? none
What type of food do you feed your betta fish? TetraBetta pellets, an occasional freeze-dried bloodworm (not daily)
How often do you feed your betta fish? 3-5 pellets/day
How often do you perform a water change? for the moment, daily
What percentage of the water do you change when you perform a water change? right now, 100%
What type of additives do you add to the water when you perform a water change? Tetra BettaSafe Water Conditioner, and for the last few days, Aq salt
Have you tested your water? If so, what are the following parameters?
(using not-too-specific testing strips right now)
Ammonia: <.02 (just changed the water)
Hardness: very low
Alkalinity: low (0-40)
Symptoms and Treatment
How has your betta fish's appearance changed? Color has gotten slightly better
How has your betta fish's behavior changed? He's perked up and become a bit more interested in his surroundings. Also, he's eating much better now
When did you start noticing the symptoms? immediately
Have you started treating your fish? If so, how? Aq. salt (mixed in a gallon jug), daily 100% water changes
Does your fish have any history of being ill? He's been like this since I bought him, so...
How old is your fish (approximately)? I bought him last Wednesday... Other than that, no clue.
Kipposhi, my red VT from Walmart, on the other hand is doing wonderfully, even though it looks like he's started tail-biting... One small chunk was missing from his tail yesterday, but he hasn't made any sign of chasing it or biting it more since I noticed it. I'm going to do my best to keep his water clean while it heals.
And sorry... I know this post is really long...
