I have had my betta fish for about 2 years now and have never had a problem, but I decided today that I wanted to give him a housing upgrade. So I went to the store and bought and acrylic tank with a filter, air pump, and led
lighting. The tank looks really nice, but when I put him in there and turned on the leds, he started flaring his gills like I've never seen before (super ugly btw), and biting and lunging at the side of the tank. Should I get a different tank? If it because it's acrylic and not glass? What can I do to fix this?
