get enough air for the fish. When a pond is not frozen, oxygen from the air is
passing into the surface of the water as soon as it is used by the fish in the pond.
When a pond is frozen, this process is almost stopped. Of course the water
can get a little oxygen at the edge of the ice, or through airholes.
But the best hope for the fish is new water which comes into the pond
below the ice from different springs or streams and which brings enough oxygen
for the fish in the pond.
And you may be sure that if the water in the pond does not get enough
oxygen for the fish, the fish dies.

KISSING GOURAMI
This fish has been publicized both as "kisser" and as an industrious eater of
all kinds of algae. The latter claim is much exaggerated. The purpose of the
kissing is not known. Some aquariusts say these fishes annoy others by sucking
at their sides. The larger ones do persecute the smaller of their own kind. Only
one or two in a "community" tank seems best.
Breeding begins at 5-inch size. They embrace like other Gouramies, build no
n«8t and have from 400 to 2,000 floating amber eggs, pinhead size. The young
hatch upside-down in a day. The parent may eat eggs, but completely ignore the
young. Babies need Infusoria for a week, followed by newly-hatched brine
shrimp or sifted live Daphnia. In two weeks, fine floating food, thereafter they are
surface feeders. Adults like powdered oatmeal with ground dried shrimp; also
crumpled dried spinach. They have few diseases, but weaken if kept cool or not
fed several times daily. Prefer a temperature of 75-82° F. Thereare two color
strains: silvery green and a pinkish, iridescent White. It is the latter strain that
does most of the breeding. There are no external differences in the sexes.
