I have a catch 22 problem with the plant of fertility from isola. I bought it when I was still having fish die as babies and wanted to be sure I was getting the most reproduction value from my fish but now I don't need two fish from each pairing as I am trying to make more new breeds not money. With the limited tank space just one per match is sufficient. Is there anyway to delete it or just keep it in one or two tanks? If not perhaps this can be kept in mind for future updates. Thanks!
