No one has gotten dropsy in about 3 weeks or so. They don’t seem to fight. The odd chase but with the amount of plants it only lasts like 10 secs. I read that you should keep the numbers odd and around 5 in a 20g with dither fish. That’s why I kept adding. I work in my fishroom so I keep a close eye. I haven’t see any fights or stress signs other then apparently dropsy? So much to learn.
