Bleher's Rainbowfish (Chilatherina bleheri)

Quarantined rainbowfish for planted aquariums and carefully selected community setups in Canada.

Bleher's Rainbowfish is a larger, elegant rainbowfish known for its graceful body shape and colourful mature display. It is a strong choice for aquarists who want a more uncommon rainbowfish with presence, movement, and natural schooling behaviour.

Why This Fish Stands Out

• Less common rainbowfish with strong specialty appeal
• Peaceful active swimmer for larger planted displays
• Attractive mature body and fin coloration when settled

Aquarium Setup & Behaviour

Provide a spacious, mature aquarium with open swimming space, oxygen-rich water, and plant cover. Larger rainbowfish need more room than nano schooling fish.

Best kept in a group. Larger groups help rainbowfish feel secure and encourage better display behaviour.

Feeding

Use quality flakes or pellets plus frozen/live foods. A varied diet supports growth, mature colour, and long-term condition.

Natural Colour & Livestock Integrity

Mature colour is developed naturally through age, health, diet, and social display. No hormones are used by Topick Aquarium for artificial enhancement.

Topick Aquarium Livestock Standard

All fish at Topick Aquarium are carefully quarantined and conditioned to our stable local tap water before sale. Although this species may have different natural habitat preferences in the wild, we focus on stability, gradual acclimation, healthy feeding, and mature aquarium systems before fish become available to customers.

Frequently Asked Questions

Is Bleher's Rainbowfish rare?
It is less commonly available than Neon or Boesemani Rainbowfish, which makes it a good specialty choice for rainbowfish keepers.

Does it need a long aquarium?
Yes. It is an active swimmer and should have enough horizontal space for natural movement.

Why buy a group instead of one fish?
A group helps reduce stress and makes rainbowfish display more naturally.
