I know that sometimes bettas need a while to adjust to new environment, new water, etc. but with two of my last 3 bettas having a lot more trouble than I would expect, I don't think its just the acclimation that's the problem. My first rescue died, and I have no idea why. Now I've got a double tail, who seemed perfectly healthy at the store, drop in condition rapidly. Will explain at the end of the post, after the questionnaire.
What size is your tank? 3 gallons, though its only got about 1 gallon of water because he's not really moving around much
What temperature is your tank? 78-80F
Does your tank have a filter? no
Does your tank have an air stone or other type of aeration? no
Is your tank heated? Yes
What tank mates does your betta fish live with? none
What type of food do you feed your betta fish? I've tried NLS and Omega One pellets, as well as Betta flakes and frozen bloodworms
How often do you feed your betta fish? He's not eating. Fed him once on day one, got him to take two pellets in the evening. I try morning and night.
How often do you perform a water change? Every day
What percentage of the water do you change when you perform a water change? 100%
What type of additives do you add to the water when you perform a water change? Stresscoat
Have you tested your water? If so, what are the following parameters?
Nitrite: between 0-2ppm on any given day (I can't fix this, its my water chemistry. I can get 5.0ppm spikes in 24 hours, and I have threads asking about this)
Nitrate: 20ppm out of tap
Symptoms and Treatment
How has your betta fish's appearance changed? Extremely clamped, and his stomach has changed to a pale white color
How has your betta fish's behavior changed? Not active, floats or hovers at the bottom. He won't flare anymore - He'll stick out his gills like he wants to flare, but his fins stay clamped
When did you start noticing the symptoms? Two days ago (day after purchase)
Have you started treating your fish? If so, how? No - I don't know what to do
Does your fish have any history of being ill? New purchase, so no?
How old is your fish (approximately)? New purchase, so unknown.
When I first purchased this fish, he was a flare monster. Flared at anything and everything. This morning I got him to flare full at me, but when I got home from work, he would only flare his gills, not his fins. That's what got me worried about him. It wasn't the not eating, it wasn't the inactivity, it was the lack of flaring like he used to. I've tried a couple times with a mirror, and even a few times with another male that I was changing the water for, but I couldn't get him to flare at me like he used to.
On top of that, I had a rescue about a week ago that died within a few days, showing the same kind of symptoms. I don't know what happened to him, he just kind of... died. He had an issue with a gill cover, so I chalked it up to previous problems on top of the stress from acclimating to new water, new habitat, etc. Now that another new, and once obviously healthy, fish is doing the same things he did, I'm getting really worried. I don't know what to do. I'm still offering food, even though I know he won't take it, just in hopes that maybe he will.
