I bought my betta at Petsmart about 10 days ago. He seemed just fine until 2 days ago. So here's the requisite background info:
What size is your tank?5 gal hex
What temperature is your tank?about 80
Does your tank have a filter?yes
Does your tank have an air stone or other type of aeration?no
Is your tank heated?Not using heater ATM. We're at 80 without it
What tank mates does your betta fish live with?None
What type of food do you feed your betta fish?Hikari pellets
How often do you feed your betta fish?2 pellets 3x day
How often do you perform a water change?once a week
What percentage of the water do you change when you perform a water change?< 50% (about 2 gal)
What type of additives do you add to the water when you perform a water change?Prime
Have you tested your water? If so, what are the following parameters?
Symptoms and Treatment
How has your betta fish's appearance changed? Coloring, fins, all look normal. (not clamped or frayed) Gills seem to be showing more than when I first got him.
How has your betta fish's behavior changed? Lethargic, moves slowly, not eating, alternates between resting on bottom and resting at the top. Also seems to be twitching sometimes.
When did you start noticing the symptoms? 2 days ago
Have you started treating your fish? If so, how? So far, I just did his 2nd Partial water change yesterday, and floated a couple of oak leaves, since I had access to some.
Does your fish have any history of being ill?I've only had him for less than 2 weeks. He was perfect until 2 days ago
How old is your fish (approximately)? Don't know. He's obviously not a baby, but as a Petsmart fish, I would guess he is still fairly young.
So, that's it. A lot of laying around, sometimes twitching when he does move around. No eating. And he loved his food! He had learned right away to come when I opened the lid to feed him. I couldn't tell you what his poop looks like, because in a week and a half, I've never seen him do it.
Let's see if I can post a photo of him:
Any ideas as to what's wrong with him? What should I do to help him?
