Butterfly Neon Yellow Danio (Danio rerio var.)

Quarantined danio for planted and community aquariums in Canada.

The Butterfly Neon Yellow Danio is a longfin ornamental Zebra Danio variety selected for bright aquarium colour and active schooling behaviour. It brings strong movement and visibility to planted and community aquariums, while retaining the hardy, energetic nature of classic Zebra Danios.

Why This Fish Stands Out

• Bright neon yellow display colour with flowing butterfly-style fins
• Hardy active danio suitable for many community aquariums
• Excellent movement fish for planted tanks with open swimming space

Aquarium Setup & Behaviour

Provide a mature aquarium with open swimming space, stable filtration, and a secure lid. Danios are fast upper-level swimmers and may jump when startled.

Best kept in a group. Group keeping improves confidence, reduces stress, and creates a more natural schooling display.

Feeding

Feed quality flakes, micro-pellets, and occasional frozen/live foods. These active fish benefit from consistent feeding and good water movement.

Natural Colour & Livestock Integrity

This is an ornamental aquarium colour variety, not a wild-type natural colour form. Colour comes from the line itself and healthy conditioning; Topick Aquarium does not use hormones or dye to artificially enhance fish colour.

Topick Aquarium Livestock Standard

All fish at Topick Aquarium are carefully quarantined and conditioned to our stable local tap water before sale. Danios and killifish can come from very different natural habitats, but stable water, gradual acclimation, species-appropriate feeding, and a mature aquarium are more important than chasing exact wild parameters.

Frequently Asked Questions

Is this a wild-type Zebra Danio?
No. Butterfly Neon Danios are ornamental aquarium varieties of Danio rerio with selected colour and longfin traits.

Should Butterfly Danios be kept in groups?
Yes. They are active social danios and look best when kept with others of their kind.

Can they live with slow long-finned fish?
Use caution. Danios are fast and energetic, so very slow or delicate long-finned tankmates may be stressed.
