Kribensis Fry

[cjohnston]

On the subject on fry, my Kribs have bred once (it was there first time) but unfortunately, lost all their fry.

They are starting to look interested again. Is it possible to remove say 10 of the fry to ensure some survive. I know that you shouldn't remove all fry straight away.

Kribs are usually very good parents. It may take them one or two attempts for the parents to get their behaviours in sync with each other, but sooner or later they will. Once that happens, unless you have a lot of fish-eating species in the aquarium, you will be able to watch them care for their brood, and easily pull out a few dozen if you want to raise them yourself.

One warning: pH is the key factor in sex ratios within krib broods. You need pH 7.0 to get equal males and females. A higher pH, all males; lower pH, all females. Broods of just one sex are difficult to sell to tropical fish shops. So if you don't have pH 7.0, go buy some pH buffer before the fish spawn again. Or better yet, adjust the balance of hard and soft water in the aquarium and a bit of peat to the filter to get things just right.
