RE: bent spines/was Winter 1967

Brian, I think we may have a bulls-eye here. I'm humbled and grateful. I've used aged water in rubber
maid containers and have been lacing the hatching tray with greenwater from a 4 gallon Sterilite container in a south window. One or both may be the culprit. The eggs I got from an Oregon breeder
that is first rate, never had problems till now (except for Fp gardneri Mamfense Ossing due to my own
ineptitude.) Which of course brings me round to what containers are safe for this kind of thing? Or is it
the heat and intense sunlight that is accelerating the condition of phenols? Thank you and to all for your
insights and experience.

Bill

ps as a sidebar, I've never mastered the art of greenwater like Scott Davis: the first shipment of killies in
the hobby included this bag of vibrant green-yellow water teeming with life when the sun hit it.

Interesting. Someone I know in Europe was at one time having trouble with
bent spines in almost all of his fish. It turned out that the culprit was a
plastic tub used for maturing water (for water changing purposes). If I
remember correctly, the problem was put down to phenols leaching from the
plastic into the water.
