As much as I would like to add another school, I think fishprotecter's idea is better. I do 1-2 water changes a week, each consisting of 4 gallons. But how many more Pink Jewels can i add? I think 10 would be a nice number, but it would be pushing it a little.You could go with a small shoal of 6 harlequin rasboras, or 8 of any of the microrasboras.
With this increased bioload, I would recommend that you bump up either the frequency or the size of your routine water changes, if not both.
