Is a rearing tank a special kind? Filterless?
a rearing tank is just a spare tank you put the baby/ young fish into so they can grow up without being eaten by other bigger fish.
Oh was thinking about a breeder tank.
Won't they get sucked up into the filter?
Just to be on the safe side, I will post some pictures later. I have a few snails to relocate.Use an air operated sponge filter in the breeding and rearing tanks so the babies don't get sucked up.
You can use a plastic storage container or any glass aquarium as a rearing tank.
