Sometimes called “bubble-nesters” because of their ability to construct a nest of floating bubbles in which to lay their eggs, the Labyrinths are well represented in aquarium culture, although not all make good aquarium fish. The gouramis and Siamese bettas are perennial favourites, however, and bring elegance to the aquarium community.
The Lace or Pearl Gourami (trichopodus leerii) is one of the larger fish to be frequently seen in community aquariums, admired for their peaceful and tolerant nature, as well as the attractive all-over covering of pearly white dots, set off by an orange-red throat and long graceful feelers.
A perfectly finned male Siamese Betta (betta splendens) is nothing less than stunning. Simply dry food feeding is not enough for them, and some live or frozen meaty food will be needed for success. It is also essential that there are no boisterous companions in the aquarium who might nip the long flowing finnage, or generally harass the betta. Ask for advice about this before you buy one!
