I have been breeding tropical angel fish of different strains for more than 6 years. Aside from being a great hobby, as a scientist it has provided me with a rare opportunity to study the cycle of life in an aquatic environment. In particular, I was fortunate to observe their mating behaviors and their methods of parenthood, which I observed to be very devoted and caring.
Here is a video I made from my breeding setup for you to enjoy! you can see the progression of the fry from embryos and fertilization up until young adulthood.
