Licorice Gouramis
All the licorice gouramis of the genus Parosphromenus that are known live in stained blackwaters. Note, however, that blackwaters aren’t really black, but a dark red-brown color, produced in part by peat-like materials but mainly by the decomposing leaves of trees and scrub that grow close to the banks. These dead leaves accumulate in multiple thick layers and release numerous substances, especially humic substances, which prevent any noteworthy population of bacteria in the water. These substances are very important to the health and well-being of the resident fishes, and often even essential for their survival.
Successful Breeding of the Sunshine Pleco
The beautiful Sunshine Pleco is native to the middle and lower Río Xingu. Juveniles and half-grown specimens live in water depths of 3.28–9.8 feet (1–3 m), while adults inhabit the very dark environment of deeper water. To replicate their natural environment, we keep our loricariid catfishes in a darkened room; the only light comes from one open door. Only during daily maintenance and feeding do we turn on a dim light. We are sure that this is a major element in our success, and not just with this particular catfish species. Obviously, it would be impractical for the average aquarist to keep fishes in pitch-dark rooms, but it is worth trying with species that have so far resisted attempts to get them to breed.
