A few weeks ago, this finally paid off and I was able to photograph my first fry; Ancistrus L159.
This resulted in this serie of pictures:

It shows the development of L159 from the day it hatched to the age of 5 weeks old. I took the pictures with a fixed interval (5 days) and paid a lot of attention to proportion, so you can also see how much it has grown in this period.
I'm hoping to do a lot more of these, but unfortunately I only have a small number of tanks and different species. If anyone in The Netherlands can help me with other species, please sent me a message.
