Hi Glen, I'm afraid there is not much good news. Usually these fish either do or don't when it comes to prepared foods. With Salarias fasciatus it is really important that they are excepting prepared foods before you bring them home. Once feeding they are a hardy fish. Unfortunately, some are strict herbivores for reasons unexplained.

You could try gut-loading some live brine shrimp with selcon. If this doesn't work then it may be best to find someone with a fairly large tank and filamentous algae or diatoms.

One other thing, try to avoid scraping the glass. How big is your tank by the way?
