Thus, certain fishes related to the wonderful Anabas—the perch that climbs trees!—make nests of bubbles, in which the eggs are placed! The Gorami and the beautiful little 'paradise-fish', for example, built floating nurseries of this kind, the bubble-raft being made by the male. In the case of the paradise-fish these bubbles are blown so that the enclosed eggs are raised above the level of the water, where they remain till hatched! This raft, although it has been seen many times by travellers, is so frail that it cannot be preserved, and has never yet been drawn by an artist, so that we can only show the fish that makes it.
