congrats bro!
just some questions..
1-why din use some other hatching devices?since the eggs are so sensitive to water flow,maybe next time can try egg tumblers that tangan keepers use?
2-maybe next time if there are such cases whereby you are waiting for something to happen,just leave a video cam by the tank to record when you are not around?(provided you have one,even dun have,surely one of the bros here have i geuss)
just my thoughts (:
cheers!
