Been a minute since I ve posted on here for good reason. Been working on my 125 and my cichlids lately. Had a spawn of red jewels that I'm now growing out. This thread however is about tumbling zebra eggs. I did my first ever egg stripping an placed the various eggs from 2 different zebra females into 2 tumblers. I believed the tumbler air pressure was up to high to begin with as it was a whirling durbish in there and later I dailed it down so that they move a little and some swirl in a circular fashion. As a result some of the eggs have changed shape to a round top with a cone shaped bottom which is darker in color than the top. A 2 toned egg. Am I correct in saying I damaged the eggs and they are no longer viable ? Will try to snap a photo but maybe a little difficult.
