Hi! I suspect my betta has a fungal infection, although it may be something else. I'm starting a dip treatment with Methylene Blue, as stated on the bottle - 5 teaspoons per 3 gallons for 10 seconds. I've been searching but can't seem to find the frequency of the treatment. I'm thinking of doing it every other day. If it's safe I may do it every day.
What size is your tank? Half gallon. I know it's small but I will get a bigger one once he's healthy.
What temperature is your tank? 22C. I know it's not ideal so I will think of getting a heater.
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 and no live plants.
What type of food do you feed your betta fish? Pellets mostly (Betta Bio-Gold). Bloodworms sometimes (Nutrafin basix).
How often do you feed your betta fish? Once a day.
How often do you perform a water change? I was doing it weekly but now every two days as part of treatment.
What percentage of the water do you change when you perform a water change? Used to be about 66% but now it's 100% as part of treatment.
What type of additives do you add to the water when you perform a water change? Nutrafin Betta Plus water conditioner. Also half a teaspoon of aquarium salt now as part of treatment.
Have you tested your water? If so, what are the following parameters?
Ammonia: It was 4ppm so then I started doing 100% changes every two days. It's about 0.5ppm on the second day now.
Nitrite: Did not test.
Nitrate: Did not test.
pH: Higher than 7.6 (max on colour chart, but seems to be a little deeper blue than that even)
Hardness: Did not test. Assuming hard since the pH is high?
Alkalinity: Did not test. Doesn't the high pH mean it is alkaline?
Symptoms and Treatment
How has your betta fish's appearance changed? Paler in colour, whiteness under/behind the gills and under the head (not spots), and completely clamped fins.
How has your betta fish's behavior changed? Inactive and not eating. Stays in corners with head at the surface and body drooping. Was not eating at all for almost a week but last two days he had a couple of pellets. But he's having a hard time catching the food, like he can't see or smell it properly. He was also darting at times and twitching a little, but I haven't seen him do that in a couple days.
When did you start noticing the symptoms? 3-4 weeks ago with the lethargy. At first I thought he'd get better by himself.
Have you started treating your fish? If so, how? As mentioned.
Does your fish have any history of being ill? No
How old is your fish (approximately)? 7 months
He seems to be doing a little bit better in the last two days in terms of colour and eating. But otherwise he's still inactive, clamped fins, and the whiteness. I did one dip with Methylene Blue yesterday so far.
Once he's healthy I will get a bigger tank and not let the ammonia go so high. I'll also try to get a heater. I will also gradually lower the pH. I don't want to do it now while he's sick because the fluctuation might be too much for him. Or should I do it now? Derailing a bit here but what is a good way of lowering the pH? I've read that pH Down is not good to use.
Is the water conditioner supposed to affect the pH as well? Or just neutralizes chlorine and other heavy metals?
Thanks a lot!
