I'd probably get a companion at least two inches, but not so big as to add
a lot to the bio-load. You've had Harold for six years, so you obviously
have a good maintenance routine going.


Thank you all for good advice. I think I will come up with one more comet,
maybe not quite as big as Harold, but not small enough to be Harold's meal.
I am not sure how I will arrange a quarantine - just not enough room for one
more fish tank (I have 55 gal and Harold's abode). I will probably add some
preventive to the water at the same time I add the fish, and watch it
closely to make sure nothing develops. There is a small, locally owned pet
store here in town, and they keep their fish wonderfully well, I have never
had problems with fish bought there.

About maintenance, it was a chore until I devised an internal biofilter. The
water conditions magically improved after about 5 weeks. Anybody interested
in making a biofilter out of the stuff you probably already have at home?

Love to all, - Maggie's Mom.
