Poor water quality can really stress out your betta, and with daily water changes, you should be able to dilute any chemicals or toxins that might be building up in the tank. It's possible that your nail polish, or even other chemicals like perfume or deodorants, could be affecting the water quality. The daily water changes should help to flush these out and might just do the trick in reducing your betta's stress.

I'm not surprised you're seeing issues with a 2-gallon tank. Upgrading to a 10-gallon tank will definitely help dilute any chemicals that might be affecting your betta.

Lately, though, he's been acting really skittish. I hold my finger up to the tank and he darts away or backs off. I've been racking my brain trying to figure out what's causing this, and I'm thinking it might have something to do with my new nail polish - it's this shiny holographic stuff from Sally Hansen called "Let's Get Digital". He's also started biting his tail, and it's really damaging his fins. And on top of that, his color has changed - he used to be this deep blue, but now he's more turquoise-ish. I'm doing my best to take care of him, but I'm not sure what's going wrong. I change the water in his tank every week, but I don't have the money to get a water tester. Any ideas what I might be doing wrong?
