No, I meant tablets in the first place. Sera O-nip is one. I used it on my loaches and they click loudly but they also click when I used shrimp pellets.Lupin.. what do you mean pellet foods? I feed brine shrimp pellets and earthworm pellets, is that what ya mean? They get algae wafers too, and i usually do frozen food every night... and i'm *trying* to get them to just taste the veggies. No luck yet.
