The Royal Pleco L191 is a stunning addition to my aquarium. Its vibrant red eyes and striking coloration stand out in the tank. It’s active but not aggressive, and it enjoys chewing on driftwood. Easy to care for with proper water conditions. A true showpiece for any freshwater setup.

I’ve had this pleco for six months now and it’s thriving. The coloration is vivid and the fish is very calm. It doesn’t bother other tank mates and is a great wood eater. The dorsal fin and pectoral fins are impressive to watch.

Looks beautiful in the tank. The red eyes are a standout feature. It’s a bit shy at first but settles into the environment well. I do need to provide plenty of driftwood for it to eat, but it’s worth the effort.
