Martin, you are lucky and you behave consequent: I do not think it is necessary to change water every two days. But it is by far better to go on like this than to become lazier now. For it’s a common thruth that one likes to believe that things could be easier and work nevertheless. That will work for some time, but then often the turnover happens …
And I think that “Finke’s rule” has probably come to its end by now. It’s a good rule but it works for a certain time only, and then the last fish has been detected. But 10 young is quite a good result for the first time!
So congratulations! Now we have to hope that there are both sexes. That is not self-evident. We had spawning with 100% males or with 100% females … The smaller the number the bigger the possibility of a one-sided result. But perhaps you are lucky in that respect, too. I am inclined to believe that the fish in the foreground with the light edges of its dorsal could develop into a male. It’s an interesting business to ask who could recognize the sex as early as possible …
