Catching Kribs (or anything else)
Carlos,
I wish I had an easy answer for you! I ran into a similar problem
with kribs. My pairs were reproducing much faster than I could remove the
young. I somewhat solved this by adding more west African cichlids. The
predation reduced krib survivors to just a few of each brood. These were
easier to deal with. On the negative side, the spawns of the other
cichlids (Nanochromis spp. and Pelvicachromis taeniatus) were also severly
reduced.
I finally gave up and removed all the cichlids to seperate 20 long
breeding tanks. However, there are still three kribs and two P. taeniatus
in the tank (I could not catch them). Eventually I'll re-aquascape and
will catch them then. I hope they do not spawn in the meantime!
The food in the net trick worked well for me. Do not feed for
three or four days before you try it. Another trick is to leave a fish in
the net (hanging in the water) and scoop up anyone that comes to
investigate. I have not tried traps, but would be interested in hearing
your ideas and results. I have also turned a predator loose in the tank.
Place a hungry large catfish (I used Mystus armatus) in the tank. They
will eat all the fry and then can be removed much easier than the fry ever
could. I would not suggest using a large cichlid for this task as they may
decide to rearrange your tank.
As you will soon see, kribs are very prolific little fish. We talk
about what fishes are suitable for a heavy planted tank all the time, but
we usually speak of plant friendly or non-friendly fishes. Removing a fish
from a heavily planted tank can be near impossible. So some fish may not
be suitible simply because of their fecundity.
