So, my Betta has barely ate all week (sunday through thursday night).
He's hiding inside his big pot a lot (he rarely plays with the pot). He also swims away if I come close to the tank.
The water temperature is a little higher than usual but it was a gradual increase (it's summer here) but not outside the 'comfort zone'.
I tried a 50% water change & alternating the food between pellots & dried blood worms but he barely even touched anything (not even the blood worms which he ate even when he had a bacteria infection).
I don't know if he's sick or stressed. He's in a 15 liter tank with a filter (noramlly a heater but because of the heat, it's turned off). He's in it alone & I tried putting a mirror up to the tank, which he has lots of fun showing off his beard & how tough he is noramlly, but didn't do anything.
I'm going to take a water sample to the aquariam shop for testing but I wanted a few more ideas when I go incase the water's fine (which it always has been in the past).
