Cardinal Eggs

[Dude]

hello

my cardinals have been showing signs of sprawning for a while now

today i noticed eggs scattered about the tank (on walls and plants)


i know its the cardinals because they are the only fish i have more than one of

my other fish are a plec BN and a otto

is there any chance that the eggs will hatch and survive?

In clean water, many egglayers will scatter eggs. Predation by the parents and other occupants will take care of most of them. Cardinals are a blackwater fish, and the chances of the eggs hatching in tapwater is very small. The Calcium ions, (mostly, Magnesium to a lesser extent), react with the egg shell making it to tough for the fry to break out.

You need almost zero hardness to get a good hatching of blackwater fish. Such water is very unstable and can swing wildly, (and fataly), in pH in a very short period of time.

Cardinals are egg scatterers, their eggs are only weakly adhesive, they should not "stick" to plants and tank sides.
