Goldfish grow pretty quickly, but if you find the number of minnows down by
one or two you can move them to a ten gallon which would be cheap to set up.
I've seen complete aquariums with filters for under $30. White clouds would
be good companions because they are coldwater fish and compatible in that
way. A loach or catfish might work, but you'd have to see if anyone has
succeeded with the combo.


weather loach are coldwater, and from what I've heard they and the
goldfish leave each other alone. It's a combination I'm about to try,
too - I'm looking forward to it. goldfish to eat the plants, and weather
loach to dig them up ;-)
