Had a betta for 3 months now since we picked it up from PetSmart. 10gal tank, heated to 80, yada yada yada. Now it's grown healthy, it's tail filled out, eats like a pig. Was labled as a half-moon but when the fins filled out, it turned out to be a veil-tail.
Last night I did a 75% water change like I always did, used prime for new water, etc.
This morning it is acting weird. It always clamors to the front of the tank when someone is near, but since the water change, it's staying at the back of the tank. Cant even feed it because it won't come to the front.
Did I do something wrong?
