Thanks. It only took the HBG and HSB a couple of days to catch on to the feeding and they behave exactly as you describe when I get to the pond. I’ve been hand feeding them every morning and evening and they certainly know the program. Their growth rate is astounding.
I’m using the Optimal starter #2, which sinks, but I’m not sure how much, if any, actually makes it past the other fish and stays on the bottom long enough for the catfish to find it. I don’t mind waiting until the catfish catch on, it just surprises me to not even catch an occasional glimpse of what should be such a visible fish. They must just be staying in the deeper water, at least during daylight hours. In some ways it’s kind of neat having something new to look forward to when they do finally start to show themselves.
