Before you choose from this collection
ShowHide
Compare Boesemani, Dwarf Neon and other rainbowfish with Forktail and Paska’s blue-eyes and Threadfin Rainbowfish. The rainbowfish label covers different adult sizes, feeding and water needs; use the exact named fish when planning your aquarium.
Plan suitable groups and swimming space alongside your existing stock. Colour can change with age and conditions, but a juvenile photograph cannot promise a particular adult appearance or sex. Check the listing for the size and any sex explicitly supplied.

Frequently asked questions
Age, sex, lighting and conditions can affect appearance. A photograph is useful for identification but cannot promise the exact colour of every fish supplied. Check the form and size, and ask us if a specific feature matters to your choice.
Plan a suitable social group for the identified species, with adequate adult swimming space and feeding access. Smaller blue-eyes and larger rainbowfish should not share a single stocking formula.
Compare the selected species, supplied size and sale unit on each listing. Budget for an appropriate group; the cheapest individual price is not the cost of a complete stocking plan.
Some can suit a carefully matched community. Compare adult size, activity, water and feeding needs; larger fast swimmers may outcompete small, slow-feeding fish. A peaceful label alone does not establish compatibility.
Use the exact species and adult swimming needs to choose tank dimensions. The smaller size being sold is not its adult requirement, and one minimum volume cannot cover the whole rainbowfish and blue-eye collection.
