Let’s hope he just moved the eggs 🙂 In retrospect, it might have been better to make the alterations to the tank after the eggs had hatched and the larvae were on the verge of free swimming: it would have been nice to observe the development of the eggs into larvae. Maybe next time. Hopefully the male chooses the canister again as the spawning site. I do like the concept of the natural appearance of fry in a well established aquarium and am quite satisfied if that will work in this case. I can also see the value of the the ‘spartan’ set-up with only one spawning/nesting site available – especially if one wants to observe the full cycle of fry development. I may try the second method at some point, but for now, it will be enough if fry will survive and grow out naturally.
PS, the male just appeared for some feeding at the front and was very vigorously chasing the female with lots of displaying – either driving her away from wherever the clutch might be – or preparing for the next spawning.
