  • Water changes while fish are holding?

    I have a couple of females holding (I noticed this about a week ago!). It is time for my routine maintainance, normal water change, and time to change out/rinse the filter media (Eheim 2260). While there is always a chance that something could happen anyway, is it better to wait for them to "spit" or just do the normal, routine stuff as if it doesn't matter? I currently don't plan on trying to catch the babies with all the rockwork I have, I guess a kind of a Darwinian natural selection program for now  :sigh: .

    Any thoughts or suggestions?

    Keep your normal routine, you should be fine.
    So many things can be a mystery, when all we're seeking is freedom...

      I Did my water change this weekend and I did a 50% water change.  4 yellow labs and 2 red rubensens peacocks holding.   The next day all normal still none any different than Saturday afternoon.

        Steve, we usually don't let holding stop us from water changes and it seems to work out fine. Personal feeling is fresh water is less harmful than old water to fry.

          I always do a 50% water change every week, while they are holding and after they have spit. I just don't put the python too close to the rock work where all the fry are hiding. Never had a problem.

                I prefer the "darwinian" method of letting natural selection occur in my tanks as well. When I had a chimba colony breeding in a 125 long, my 16" giraffe was "darwin". I noticed that some babies came out of the female's mouths and knew to go hide in the rocks, while others randomly darted about in the front of the tank and knocked into rocks until the giraffe came along and sucked them up. The babies that survived, and there were TONS, I mean an incredible number, were mean little suckers. They ate aggressively, eating pellets as soon as they were freed from the mothers mouth and later they bred very well. In fact, one individual said he saw 2"-3" juveniles I sent to him breeding almost immediately. My thoughts are that letting things go naturally in the tank allows the babies to understand the breeding of their parents and keeps the gene pool in top condition. If I was wanting a profit and to maximize my yields I would have stripped and tumbled, but then the gene pool would have been polluted with slow and less than optimal babies that grow into slow and unintelligent adults. Why is it that the unintelligent breed so much more? Anyone seen Idiocracy? Awesome....

                  I believe in survival of the fittest!

                  I watched a single awol male pick of two mouthfuls in the same day....about 30+ fry...but I felt they were bound to lose their life since every last one of them dart out into the open.

                  Also watched some of my older Ilangi fry corner a smaller one and kill it off.

                    I totally agree with the Darwin version, but I didn't want to be the one to "kill" them. One female opened up her mouth, and most, if not all, the babies were eaten by opportunistic fish all around her. My Yellow lab is still holding (and hiding). I have had fish holding before, but I never seen a fish with her throat and cheek areas so full
