I am worried that as my angel continues to grow, he may start going for my narrow wedge rasboras (biggest seems to be 1.5"). Already, during feedings s/he gets VERY feisty and has almost snatched up a rasbora thinking it's a pellet. I currently have 12 in the tank, and with my newly revamped 10g empty, I was wondering if 12 would be overstocking a 10g tank? I have an AquaClear 50 on the tank and do weekly water changes, so waste build-up isn't really an issue. But would the petite rasboras feel too squeezed? Just worried for their well-being lol!
