I got my Betta about a week ago and he was spectacular!!!
Now, about a week later, this is what he looks like:
I keep my water very clean (tested for ammonia, nitrate and nitrite and all came up zero), temperature stable at 79, he eats like a pig and is extremely active.
I will admit that I use an aquaclear filter and even though it was a minimum, the circulation might have still been too much, but I recently fixed that by putting some filter floss in front of the output.
Any ideas on what it could be/how to fix it?
