It requires 125 gallons tank with plenty of space for swimming.

Breeding Royal Pleco
The Royal Pleco does not breed in captive condition and little is known about their breeding habits. Generally it breeds in rainy season. The rainy season typically brings cooler, softer and more acidic water with plenty of meaty food and green foods. For breeding of royal pleco, use rain water and do major water change which influence the breeding performance. In this case 30 % water changes should be done for several weeks until the male show interest in making a cave. The added water should be a few degrees cooler than the tank water temperature and have a pH of 7.0 or slightly lower than 7.0. Before spawning, fish should be conditioned with fresh vegetables and protein foods which encourage spawning. Feeds include spinach, peas, vegetable flakes, live and frozen bloodworms and brine shrimp and carnivorous fish food. The female lays their eggs in some kind of cave. The eggs hatch in 5-10 days and about 3-4 days later fry becomes free swimming. At this time fry should be fed with green flake food, mashed and peeled peas or other baby food.
Sexing Royal Pleco
There is no visible difference between the male and female but it is possible to sex them by observing genital papilla. The female genital papilla is rounded and blunted while in the male it is smaller and have a pointed shape.
