While I appreciate everyone's responses and details of their
experiences what I'm really asking is why small to moderate scale
commercial breeders of many kinds or ornamental fish use such
immaculate and therefore artificial rearing tanks? I would think that
the type of rearing environments you or I or the other posters have
would be preferable.

Because some people believe all the nonsense about diseases spread in
anything other than sterile environment.

Uh huh. I thought there might be a real reason. If that is the logic
it totally misunderstands pathology, disease transmission, and the
role of microorganisms in heath. It is a bit bizarre of a miss when
the same ppl are relying on large colonies of _bacteria_ to run their
filters.

After 30 years breeding
fishes I've never needed to keep fry in sterile tanks. I do use clean
tanks but, as I said before, fry grow fastest with continual feeding
and frequent water changes. It's just hard work!

Makes sense to me
