Spotted Hoplo

Megalechis thoracata

In its natural habitats the Spotted Hoplo experiences a number of extreme conditions ranging from extremes of pH and hardness to a complete drying out of the ponds it lives in. When this happens the fish burrows up to 25cm into the muddy bottom and will remain there for several months until the first rains arrive. It is even commonly found in areas where human wastewater is deposited and seems to thrive under such conditions. Its lifestyle in nature results in the Spotted Hoplo being an extremely adaptable aquarium fish suited to almost any conditions. In the aquarium it is active and peaceful unless spawning when males can become aggressive. The fish has poor eyesight and spends much of its time exploring anything it can find by touch with its sensitive whiskers. This activity is a good source of interest and amusement to the fishkeeper, and sometimes a source of irritation to slower, timid fish. An interesting fish which is worthy of observation in an aquarium.
