I got my daughter a betta fish about 2.5 weeks ago, and he won't eat. He otherwise seems ok - not great, but ok. He approaches the food, but won't eat. I tested his water today and the pH is high; not sure if that would make him not eat. He ate one pellet the day after we got him, and he ate one or two blood worms over a week ago, but nothing in over a week. Here's the questions:
What size is your tank? .75 gallon
What temperature is your tank? ~76F (room temp in my daughter's room)
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? We've tried betta pellets, flakes, freeze dried bloodworms and in a last ditch effort, frozen bloodworms, since they are supposed to love those.
How often do you feed your betta fish? We offer twice a day, and I remove the uneaten food after an hour or so.
How often do you perform a water change? 2x a week
What percentage of the water do you change when you perform a water change? about 1/2
What type of additives do you add to the water when you perform a water change? dechlorinator
Have you tested your water? If so, what are the following parameters? I just tested today with a 5 in 1 strip test.
Ammonia: haven't tested
Nitrate: somewhere between 0 and 20
Symptoms and Treatment
How has your betta fish's appearance changed? No change, appears fine
How has your betta fish's behavior changed? He responds to us and seems happy and swims around when he sees us, but otherwise he seems to just hang out in his plant and not do much
When did you start noticing the symptoms? He's been that way since we got him 2.5 weeks ago
Have you started treating your fish? If so, how? No, I realize the pH is high, so I should probably do something about that
Does your fish have any history of being ill? N/A
How old is your fish (approximately)? We just got him from a pet store where they have a lot of bettas and seem to sell them very often, so I would guess not very old?
Any help would be greatly appreciated. This is my daughter's first pet, and I'd rather he didn't die!
