Common Mistakes

Keeping too few

Fork-Tail Blue Eyes are social schooling fish. Keeping them in very small numbers can make them nervous and less active.

Feeding food that is too large

Their small mouths are better suited to appropriately sized flakes, micro pellets and small frozen/live foods.

Housing them with aggressive fish

Avoid large or aggressive tank mates that may intimidate, injure or prey on them.
