Information about care

Food and feeding
Do not be fooled by the size of this fish’s mouth, they have a very narrow throat. Only smaller foods must be given to them, quality flake and live foods are ideal for them. If using granular foods, always use the smallest size.

Origin
They are to be found in New Guinea and North Australia.

Sexing
The males will have longer fins and be much more colorful.

Breeding
These fish need perfect water quality to spawn; large changes at a slightly coolertemperature will induce this. Use a spawning mop, as the eggs will need to be removed once they are laid. The fry will be very small, feed with Infusoria until they have grown slightly and then feed with newly hatched brine shrimp.

Lifespan
The expected life span for this fish is 3-5 years.

Short description
Due to the males having quite long fins, avoid keeping them with fin nipping fish. They require well planted tanks but with open swimming spaces at the front.
