Hello. I recently bought what I believe to be a female betta about a week or two ago. She, unfortunately, lives in a .75 gallon bowl with a live plant. I do weekly water changes, feed her twice a day and once a week give her a blood worm as I do with all my bettas. Yesterday she began acting weird. She just lays at the top of the bowl or at the bottom under the plant, sometimes lays on the leaves. Normally she swims up to me when I walk by or walk over but she hasn't really recently. She barely moves. She does go to the top to get food but then swims back down or just lays still. I'm at work right now and asked my mom to check on her. She says she's losing color. Is there anything I can do to fix this? I thought about buying her a 1.5 gallon. I know it's still small, but it's better than a .75 gallon bowl and has a filter. Not to mention I don't have much room for anything bigger.
