Hello, I got Archer just a few days ago and I'm pretty sure he has external parasites, though I don't know which ones. He trembles, scratches himself (so much his crowntail edges are littering the tank), is inactive, doesn't eat or show any interest in food, and has swim bladder issues.
I don't see any white spots. I think I maaaay have seen some velvet though I am unsure if that's his natural coloring. I did a 20% water change, put in some aquarium salt, and have covered his tank from light. Here are the specs:
What size is your tank? 2.5 gal
What temperature is your tank? 75-80*
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, aside from the parasites.
What type of food do you feed your betta fish? wardley betta food and the occasional bloodworm, though this specific betta has not eaten since he has come home
How often do you feed your betta fish? 2-3 pellets once a day, bloodworms twice a week at night.
How often do you perform a water change? twice a week.
What percentage of the water do you change when you perform a water change? 20-25%
What type of additives do you add to the water when you perform a water change? None (Bruce, my other betta, has lived just fine with this for months, and came from the same store as Archer).
Have you tested your water? If so, what are the following parameters?
Hardness: 120 (this actually matches what was in his cup; my area has very hard water)
Symptoms and Treatment
How has your betta fish's appearance changed? Clamped fins, very dark
How has your betta fish's behavior changed? Twitches, scratches, is inactive til I get his attention, does not eat, shows swim bladder issues.
When did you start noticing the symptoms? Tuesday night, two days ago.
Have you started treating your fish? If so, how? I have done a 20% water change, added aquarium salt, and covered the tank from light.
Does your fish have any history of being ill? n/a
How old is your fish (approximately)? n/a
Please, I beg you, just help me. :/ He's so beautiful and was so friendly, I'd hate to lose him.
