Why breed Neons? Bit of an odd choice to me, they are farmed on an insane industrial scale in the Far East and don’t really exhibit any particularly interesting behaviour due to being egg scatters.
Stuff like Angel fish, Cory catfish and betas have far more interesting breeding behaviour (to me). Getting rid of the fry is a much bigger challenge of course.
back to neons, you don’t need peat, you just need really soft water and they’ll just do it. They are prolific breeders (hence the price and popularity). The proper breeders have tanks with false bottoms that the eggs drop through but the fish can’t get to. Neons will just eat their own eggs without it or some kind of breading mop.
