About 1/2 of mine went into one tank with the L333 plecos. The eat some of them and the worms get up under the caves. Then like once per week I move the caves. The plecos feast again. It is a naked hiney tank. (bare bottom)
I have never fed blackworms. I did not know they can live underwater, wouldn't your plecos eventually get them even without you having to move the caves?
