One dead RES yesterday, no more dead ones today. The 30-ish that are left seem quite healthy.

I moved the cage next to the dock yesterday.

Been feeding chopped up nightcrawlers because that's what I had on hand.

Optimal arrived today. Mixed a couple tablespoons of that with the chopped crawlers that I fed this evening.

Noticed that a few tadpoles and some sort of water bugs had made their way into the cage. There wasn't much left of them. All of the small bits were gone.

So it looks like the 30-ish RES that are still in there are little savages and probably will do fine from here on out.

I'll continue to monitor and report.
