Snowball Plecostomus L102 (Hypancistrus Inspector)

Snowball Plecos are a beautiful, peaceful freshwater fish that are docile and undemanding and slightly smaller than some of their relatives. These Plecos are quite hardy and can quickly adapt.

The Snowball pleco is a non-aggressive species that can be mixed with other peaceful fish in a well-maintained community aquarium. However, these fish are not very social, and you must not keep them alongside other bottom dwellers, or they may fight over a favourite hiding place. Not keeping them with other plecos will also help to prevent hybridisation.

Snowball Plecos are nocturnal so you will not see them much during the day. Typically they will rest in dark caves until the sun goes down.

Snowball Plecos bodies are usually black or dark grey. Males may also have a dark brown colour with a slight tinge of red. The body colour is accentuated with large white or pale yellow spots; these spots are much smaller on the head than the body. These Plecos have splayed-out pelvic and pectoral fins as well as a large triangular dorsal fin.

Natural Habitat

Rio Negro


In the home aquarium, the Snowball Plecostomus L102 will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It is relatively simple to differentiate male from female Snowball plecos. The females are blackish-brown in colour, display white spots, are stockier and fuller than males and have almost no odontodal growth whereas males have a lot more reddish tones in its colours with white spots, have a strong odontodal growth and are more slender than females.
