I posted the video that I had seen from the co op. Its hikari vibra bites. I can not find them anywhere near me. I will have to order them from somewhere eventually. He still hits the pleco bites but wont swallow it. May just be aggressive behavior. I have two colonies of breeding snails. They are growing quite fast for me. I feed a ton though more food more babies. My lfs breeds them too they have 10 buckets in the back full of "pest" snails. They sell them for .05 - .10 cents each. I bought 200 and put them in 3 places 1/3 into each tote and 1/3 in my 40b. I ran an air pump driven sponge filter in the totes 1 got a heater 1 did not the room they are in is around 76f but the heated to is 82f. They breed faster in the heated one. You might want to try that. I cleaned the 40b out feeding about 6 per week. I really didnt mess with the totes other then to feed every couple days. I've done a wc on the totes twice. Id like to change the setup a bit to be able to change the water more often.
