A "REARING TANK" FOR PLANTS?
 

A "REARING TANK" FOR PLANTS?

Why not? Some aquarists sometimes manage to get plants to reproduce sexually, when they bloom. They use one or several cultivation tanks, in which cuttings, layering, and division of the base are regularly performed. When they are fully grown, the plants are then transplanted into a community aquarium.

A reproduction tank for plants must have specially adapted and fairly strong lighting.

The water level should not be too high, to assist the penetration of light, and the bed should be given appropriate enrichment. Miniature jardinieres can even be constructed, using jars or ice cream or yogurt cartons, for example. The filtration should be gentle, and there should be no oxygenation at all, to avoid the CO2 dissolved in the water being let off into the atmosphere. If there is not enough carbon dioxide, equipment to provide moderate diffusion of this gas into the tank is available in aquarium stores. A few fish will add the finishing touches to the equilibrium, and if you choose specimens from the same species, they can reproduce as well. These days many aquarists are enthusiastic about the reproduction of fish, but few are interested in cultivating plants, although this can be just as fascinating. The propagation of aquatic plants is easy and you can quickly build up large stocks to pass on to, or exchange with other enthusiasts.
