The first little sized tank we show is a smal special aquarium in the bedroom of a 12 jear old boy. The large image is from the begiining. Planting consists for a large percentage of fast growing plants. f.e. Hygrophyla polysperma. This was later on replaced by Cryptocorine nevelli. In this way the aquarium became less sensitive for maintainance. In this way our student keeps time for his homeworks.
