>What are the best conditions to keep rainbows. Can you be specific about
the water quality, plants, substrate, the size of your tank and any thing
else that might be relevant?
Gail, you can't say "these are the best conditions". That depends from
so many facts, that you can't say "these are the ones". Make a regular
water change and give them suitable food (that's described in the books),
don't keep them too warm, and than wait and see.
