Hello Everyone! I'm new here and new to the betta world. I recently bought a beautiful Delta Tail male betta that I named Raz at Petco a week 1/2 ago. He was perfect swimming and happy. Then I noticed his appetite was not good. I tried pellets but they would just sink to the ground and he wouldn't eat it just kept spitting it out. So I thought he is picky and bought some flakes instead. Still no appetite. Then I noticed yesterday he would stay at the bottom of his tank laying on his side on the gravel. When I approach the tank he sees me and starts swimming again but this worries me. I'm a new betta owner so any advice would be greatly appreciated.
I have a filtered 2.5 gal tank. I did use a Quick start and Stress coat then I let the filter with treated water run for 24hrs before putting him into the tank. I live in Chicago but the weather here is in the 80's so I don't believe the water temp is the issue. I plan to buy a heater and thermometer today though and get the water tested too. I took a video of my little guy to show you how he is acting. I just have to figure out how to post it. Hmmm. I only had Raz for a little over a week but I'm crazy about him and want to help him get better any way I can.
