About Black Onyx

Rich, dark color gives our Black Onyx Shrimp a bold presence in your aquarium. Their black coloration creates a striking contrast against bright green plants, lighter stone, and natural wood.

These peaceful, active grazers spend their day exploring moss, leaves, and décor, picking at biofilm, soft algae, and leftover food. They bring subtle movement and plenty of personality to a planted aquarium.

Provide a stable, established aquarium with plenty of grazing surfaces and hiding places. Supplement their natural grazing with quality shrimp food, and choose peaceful tank mates that won’t view them as a snack.

Please note: Color intensity and coverage naturally vary between individual shrimp. Some may show brown undertones under certain lighting. Age, substrate, and shipping stress can also affect their appearance.

Keep their world steady

Start with a fully cycled tank.
Provide moss, cover, and gentle filtration.
Avoid sudden changes in water conditions.

A few good questions.

For a first Neocaridina colony, a group of 10–20 shrimp in an established 10-gallon aquarium is a practical starting point. The right number depends on your tank's filtration, available food, and other inhabitants. Start small and leave room for your colony to grow.
Neocaridina varieties, including Cherry Red and Blue Dream, are a great introduction to shrimp keeping. The key is a fully cycled aquarium and stable water conditions—sudden changes can stress shrimp. Some other varieties need more specific care, so check their requirements before choosing.
Neocaridina spend much of their day grazing on algae and biofilm—the natural coating that develops on aquarium surfaces. Supplement this with quality shrimp food, occasional algae wafers, and small portions of blanched vegetables such as zucchini. A varied diet helps support growth and healthy molting.
Not always. A small colony in a mature tank may only need supplemental food every other day, while a larger colony may need small daily portions. Watch how quickly they eat, adjust accordingly, and remove leftover pellets or vegetables after a few hours to protect water quality.
Neocaridina shrimp typically live around one to two years, though lifespan varies with temperature, water quality, and overall care. A stable aquarium, suitable food, and consistent maintenance give them a strong foundation for a healthy life.
