I bought a black racer nerite a week or so ago and I don't think he's eating. He tries to eat the "algae" on the glass, but it's new tank so there is nothing there. I got him to clean up my fry tank, but of course he wasn't my 1st choice because of the lack of algae. I've given him 2 different brands of algae tablets, seaweed, and blanched cucumber, but I never see him eating any of it. If I put him on top of the food he just walks off. It is quite possible that I don't see him eating it, because he's been acting nocturnal for the past few days. The food never seems to go missing or have chunks taken off, even with fry that love anything I give him.
What should I do?
