Goldfish are cold water fish but you can expect some degree of dormancy
below 60F, with almost full dormancy at 55F (will hardly move, won't eat).
They are happy between 65F and the low 70s. They appreciate extra
oxygenation through air stones and such when the temp hits 75F. Above that,
the risk of illness or just odd and harmful reactions rises greatly. They
also prefer base pH.

I think of goldfish as little bulldozers. They will nip, plough, and tug at
anything. They particularly like to strip the leaves off cardamine and
ludwigia--not eat them, just strip them. I haven't found many plants to
survive their attentions. Swords and transplanted giant vals (raised in a
plant tank) seem to hold their own. Right now, two're working over the
giant val though and have breached a few leaves.
