Hey everyone. I've had a 20g high with a few live plants, RCS, and baby BN plecos for a good year or 2 now. I've grown kind of tired of this setup and the wife kinda wants to make it her little tank, so I agreed. We will be doing fake plants along with some small driftwood in this one. She's thinking of making it an all male guppy tank. How many could we fit in there safely? Any other ideas? Thanks!
