I hired a harlequin 1) to help deal with the huge asternia population in my tank and 2) because, dang it, they are really, really cool looking.
It turns out that either this harlequin is exceptionally good at its job, or that I am not as good of an asternia farmer as I thought I was, or both because the asternia are almost all gone now.
I'd like to keep the harlequin on as a full time employee, but would like to switch to a less troublesome food supply for it. What kinds of safe-ish stars do other harlequin owners keep for food?
