The mouth is very large and upturned, and the eyes are small. On top of the head, a large, fleshy protuberance is used to attach to submerged tree roots and branches in the wild. Males have longer, more flowing fins than females.

Royal Pleco Breeding

Royal Plecos are a popular fish for breeding and can often be found in pet stores. They are known for being one of the easiest fish to breed and are an excellent choice for beginner breeders.

The best way to breed Royal Plecos is by using a 120-gallon tank with plenty of hiding places. The tank should also have a tight-fitting lid, as they are known to jump out of tanks. The water should be kept around 72°F to 78°F, and the pH level should be around 6.6-7.5.

The female Royal Pleco will lay her eggs on a flat surface, such as a rock or piece of driftwood. The male Royal Pleco will then fertilize the eggs. Once the eggs have been fertilized, they will hatch in about 5-7 days.

The fry (newly hatched fish) will need to be fed a diet of baby brine shrimp or crushed flake food. They can be raised in a community tank with other small fish. By raising the fry in a community tank, you can help reduce the chances of them being eaten by larger fish.

By knowing how to breed Royal Plecos, you can help increase the population of this popular fish.
