Thank you for your $0.02. The only reason the subject came up in the first place is that some members of the list were trying to ensure that accurate information was being provided for those people who may not have much or any significant experience in raising fry. According to the literature, and the experiences and opinions of most of the contributors to the discussion, large, frequent water changes appear to be the accepted norm. However, there are a very few people who insist that small, less frequent water changes suffice, despite the fact that their fry seem to take a lot longer to mature. I don't actually believe in all seriousness that the experiment requires to be carried out. But it is interesting to note, the majority of the respondents who have written to express their view, believe that large water changes are definitely the best way to go. (Obtaining input from various sources in this manner, is not unlike flushing grouse out of the undergrowth.) I would be quite happy to end the subject on this note. Should someone feel the need to carry out any comparison study then it is not too difficult. Given the fact that one person is carrying out the various procedures involved in caring for the fish, the variables and parameters of their work should be a reasonable constant. Obviously, most people on this mailing list are not breeding their fish in laboratories. Yet, if the results are skewed dramatically in the direction of having much larger fry in a given length of the time, then the experiment would not be totally meaningless. At least the list archives would have the information should a newbie want to know the best method by which fry can be raised. Be happy and spawn! G.
