Yes John, I still use about 10 -5gal tanks for breeding. As a matter of fact I have about 4 small A. resticulosa in a bare 5 now with only a small box filter and just returned home from a five day vacation to find a small cluster of wigglers herded in the corner by the mother. No pots, no plants, no nothing! 4 fish no food for 5 days and I get wigglers; you go figure, I can't.
