Whole eggs, scrambled. Interesting.

I experienced a major fish kill several weeks ago, approximately two weeks after introducing 21 catfish to a new tank. All seemed fine during the interim, algae grew, the water turned green*, and then one morning, dead fish started floating to the surface. We lost 12 of the 21. Ph had spiked to over 10 - don't know why. We reacted and the survivors are doing fine. Can't explain the spike, can't explain why some fish died and others survived. The dead included the large and small siblings of a group birthed about nine months prior, meaning size didn't seem to be a factor.

*a State inspector (Tilapia license) stopped by a day or two before and indicated that all looked (and smelled) fine.
