I have had the same experience as John. If you move both fry & adults, there is a fairly good chance that the fry will disappear. In addition to the stress, I wonder if the parents no longer "recognize" the fry as their own in the new tanks. Although I recall a post that theorized that the "smell" of the water in the spawning tank was a method by which foster parents (borelli, I think it was) could be encouraged to care for a different brood, I guess there must be limitations. For example, I have had the misfortune to have fry that were sucked up by a power filter (prior to the use of a sponge covering over the intake), where they survived for a few days or even weeks. Whenever I introduced such fry back to the parents (in the same tank), they were usually immediately chased down and eaten. Somehow, the parents can distinguish these fry from the fry that they are currently tending. On the other hand, on one occasion, I separated the parents from most of the fry (because of parental fighting) for a period of about 14 hours and when I re-introduced the fry, the parents accepted them. Does anyone have any experience or information on how long parents can be separated from fry and still have the parents recognize the fry? Or do you think it is a question of idiosyncracies in parental behavior, i.e., how good a given pair of fish are as parents as opposed to an instinctive response? Also, I'd like to note that I prefer to move the adults, since they tend to be easier to see & catch - if I try to move the fry, I always find a few the next day that I missed, requiring another dip into the tank. If you are moving fry, you should use a hose, as other people have noted. I find that fry do better when siphoned out through an adequately sized hose. A hose also seems to cause less disturbance in the tank. Finally, I'd like to pose a question about water conditions of raising fry. It seems to me that the water parameters have to be "correct" for fish to spawn and for the eggs to hatch, but after the fry are free-swimming, they seem to handle varying water conditions about as well as their parents (aside from any sexing issues!) and spawning conditions no longer have to be maintained. Aside from any discussion of whether the fish are truly happy in non-spawning water parameters, has anyone noticed a difference due to water parameter changes, given that the parents are doing well and assuming no obvious negatives, like poor water quality or rapidly fluctuating conditions? If so, at what point does the sensitivity of the fry equal that of their parents? Yep, it's not that busy at work today... :) -mk ------------------------------------------------------------------------- This is the apistogramma mailing list, firstname.lastname@example.org.
