My otos have decided they hate me and find me terrifying.

First month I had them, they were out front every day, are wafers voraciously. They'd jump when I got up from my chair but wouldn't lose their minds or anything.

Now several months later I never see them. The wafers remain on the ground sadly uneaten. The little buggers only emerge at night, I wouldn't even know for sure I still had all 6 if I hadn't just caught them all and relocated them to a 63 gal, where they continue to lose their minds and zoom all over the tank whenever I approach.

What happened to our love, guys?
