Not a conflict of interest at all. Nano is barely begining breeding JD's and will take awhile to get it how he wants it. So saying to get it from a good breeder is good advice when he has none in stock.
isn't it a conflict of interest when you saw to go to a good breeder and your a breeder?
anyways, why not some pictus catfish, they are awesome bottom dwellers and will fight off any possible attacks by the JD.
