Underwater landscape

Pantanal, clear water biotope, during a rainy season. Plants with small leaves, growing densely, along with pieces of driftwood and roots of nearby tree provides good shelter for small fishes like Apistogramma sp. Nannostomus sp. Corydoras sp.

Water is full of small crustaceans and insect larvae, giving an excellent food source and encourages fish to spawn. Quite low water level near the banks (only about 50cm) of the pond keeps the large predators away. Detritus, algae and protozoa that occurs in leave litter, on the wood and plants are a good source of food for fry. Underwater live is showing its beauty everywhere. In the places where sunlight reaches the water undisturbed by trees, and uncovered by leaves, aquatic vegetation occurs in its greatness.
