Its combination of vivid coloration and constant activity makes it an impressive choice for larger freshwater community and planted aquariums.\u003c\/p\u003e\n\u003cp\u003eDespite the name \u003cstrong\u003e“Roseline Shark,” this species is not actually a shark\u003c\/strong\u003e.

Moderate to strong water movement is beneficial, along with plants, rocks, driftwood, and open areas where the school can swim freely.\u003c\/p\u003e\n\u003cp\u003eFeed a varied diet of high-quality flakes, pellets, and appropriately sized prepared foods supplemented with frozen or live foods such as brine shrimp and daphnia. Some vegetable-based foods can also be incorporated into their diet.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBehavior \u0026amp; Tankmates:\u003c\/strong\u003e Roseline Sharks are generally peaceful but extremely active. They work best with similarly sized peaceful community fish that are comfortable with their energetic swimming behavior. Their eventual adult size and activity level should be considered when choosing both tank size and tankmates.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease Note:\u003c\/strong\u003e Size, coloration, pattern intensity, and sex naturally vary between individual fish.

Because Roseline Sharks are social schooling fish, we recommend keeping them in a \u003cstrong\u003egroup of 6 or more\u003c\/strong\u003e whenever aquarium size allows.\u003c\/p\u003e\n\u003cp\u003eAll livestock from Felipe’s Fish is carefully selected and prepared for safe transport.
