How many shrimp pellets should I drop into the tank to feed my featherfin catfish? It's about 6" long now. I feed it once at night since it essentially hides during the day. :;nin2 It won't eat until I turn off the lights, so I can't go by the 2 min rule. I know fish stomachs are small, but I'm no good at guessing. :;dk So, 2 pellets? 5? 10? Anyone's guidance is appreciated. Also, same question for when I switch to algae wafers twice a week. 1? 3?
