Silver Arowana (Osteoglossum bicirrhosum)
Silver Arowana (Osteoglossum bicirrhosum)
Quarantined monster fish for carefully planned freshwater aquariums in Canada.
The Silver Arowana is a legendary surface-dwelling predator with a long body, large scales, and powerful presence. It is a true monster fish that should be purchased only by aquarists with a serious long-term aquarium plan.
Why This Fish Stands Out
- Iconic monster fish with impressive surface-swimming behaviour
- Strong display presence for very large aquariums
- Best for experienced keepers planning long-term size and feeding needs
Aquarium Setup & Behaviour
Requires a very large covered aquarium with strong filtration, open surface swimming space, and secure lids. Silver Arowanas are powerful jumpers.
Best kept with carefully selected large tankmates only when space allows. Small fish may be eaten.
Feeding
Feed quality carnivore pellets and appropriately sized frozen/live or prepared meaty foods while avoiding overfeeding.
Natural Colour & Livestock Integrity
Natural metallic colour develops with growth, diet, and healthy conditioning. No hormones are used to artificially enhance colour.
Topick Aquarium Livestock Standard
All fish at Topick Aquarium are carefully quarantined and conditioned to our stable local tap water before sale. Some oddball and specialty species still have very specific long-term needs, so we recommend matching each fish to the right aquarium size, diet, tankmates, and maintenance routine before purchase.
