I just got my betta last sunday, so three days ago. he's acting funny. when I first got him he seemed happy, like he would swim around a lot and chase my finger when I held it up to the glass and he would flare at himself in the mirror and stuff. I bought him a heater a day after I got him (after reading all about bettas on this site) and put it in the tank and acclimated him to it slowly, and so the tank is a good temp for him. he was acting lethargic last night and would stay in one place not moving for a long time before swimming somewhere else and doing the same thing. Today I fed him this morning and he hasn't eaten any of it, and also, I don't think he's pooped since I got him. I'm not sure why. here's the survey thing:
What size is your tank? 2.5 gallons
What temperature is your tank? 81 degrees
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 feed him top fin color enhancing betta bits.
How often do you feed your betta fish? I've been feeding him about four pellets twice a day, that's what it says to do on the food container
How often do you perform a water change? I haven't changed his water yet since I just got him three days ago. I'm going to do it today.
What percentage of the water do you change when you perform a water change?
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 haven't.
Symptoms and Treatment
How has your betta fish's appearance changed? His appearance hasn't changed really, except one little thing that i'm not even positive about. It seems like his side fins used to be spread apart more when he swam, and now they're really small and close together, sort of un-flared, if that makes sense. he's moving them faster and seems to be trying to swim harder right now but he's not making much progress. he keeps floating up to the top but it seems like he's struggling to swim to the bottom.
How has your betta fish's behavior changed? see above.
When did you start noticing the symptoms? last night.
Have you started treating your fish? If so, how?
Does your fish have any history of being ill?
How old is your fish (approximately)? I just got him three days ago from Petsmart.
