Betta Fish With Clamped Fins And Lethargic

[FishMakeLifeBetta]

So this is actually a post for my friends fish, who has not been doing well. He is a baby boy petco Betta she got in April. Starting about a month ago, his fins have been clamped, but they’ve gotten much worse and now he stays in the corner of her tank lethargically. He shares a tank with a female, with a divider in between them, however, the female is completely healthy and happy. There are no physical signs of sickness other than the clamped fins, and neither of us knows what going on. He eats, but not with any interest. Can anybody help?




HI'm before he got sick:

Tank conditions such as ammonia levels, nitrite levels, nitrate levels, pH and temperature are required.

Also what is the tank size? I would say at the very minimum 5 gallons is required for 2 fish.

Just because the other one is okay, maybe the young fish is more sensitive. Definitely measure all these levels if your friend does mot already know them. If any of these levels are high, you can add seachem prime and do a 10-20% water change. If all these are okay, fish can be sensitive to pH changes. I would make sure the pH of the water she is adding is the same as the pH of the tank. Also make sure temperature is the same.
