How often to feed Ottos?

Let's see... They are TeatraMin Tropical Tablets. "The Rich Mix" for bottom feeders. It just says it contains essential nutrients and stabalized Vitamin C. The ingredients list algae meal and shrimp meal. I know I was looking for one with Spirulina (?) and vegetable-based, because that's what the tag beneath the tank said they ate. I asked the sales-lady, but she barely glanced at it before saying "yeah". I don't know that I would've trusted her opinion either way...

Tonight is the first time we'll try feeding. Do you think these pellets are okay? I knew I should've come home and looked it up instead of trusting the tank's tag, but I don't get out to Petsmart very often, so I was winging it while I was there (I went for gravel and something else, figuring I might pick up an Otto and it's food while I was there).

Thanks for all your help guys and gals!
