Polyacanthus cupanus Var. Dayi Original Painting by Francis H. Goodby Among the most interesting of the many fishes that may be bred in the home aquarium are those of the genera Macropodus, Betta, Trichogaster, Os- phromeniis and Polyacanthus of the group Labyrinthici—the labyrinth- gilled fishes. More so than with many other fishes it is necessary to understand the conditions that favor the successful rearing of the young. We all know that they build a foamy nest of bubbles; that the eggs are placed in this nest; that they and later the fry are guarded by the male; that the female must be removed immediately after the eggs are expelled, and the male when the fry begin to leave the nest. That is all. More than this is not generally known, and these bare facts are not sufficient to insure suc- cessful propagation. The first essential requirement is a large tank, as these fishes cannot be bred in a small one. An aquarium not less than 30x15x12 inches should be allowed to stand over winter without fishes and containing a good growth of plants, algae covering a part of the glass, plenty of Riccia or other floating plants, and but four inches of water. When spring ar- rives give the tank plenty of sun, but do not introduce the pair of fish until May or the beginning of June. With abundant sunlight it will develop suf- ficient Infusoria for 300 to 500 baby fish until they are large enough to devour the smallest Cyclops and Daphnia. The tank can easily be kept in condition by occasionally throwing a little dried and powdered lettuce into it. As soon as the fry are large enough to take small live food, sifted Daphnia and Cyclops are to be given, later large Daphnia,
