    Diet: carniverous. Live microfoods, will easily adapt to dry foods.

    Breeding: They are an egg scatterer, and if provided with a mop or sufficient moss or plants, they can lay eggs, however they need to be kept from them by a division in the tank, or removal of the eggs or fish. They will also not provide any care, so removal of the parents is still the best plan.

    Tank companions: They hunt red cherry shrimps as adults.They would try for crystal red adult shrimps, but ay not be able to kill them unless working together. They would certianly take shrimplets until near adult size. They are OK with Caradina typus, which are much larger. I removed the Gold line pencilfish from my shrimp tank.

    Other microfish are suitable tankmates. I have kept them with bororas; danios; chocolate, liquorice & sparkling gouramis; green neon & ember tetras; male endlers and royal whiptails.

    They will intimidate smaller tankmates, such as the bororas, who will become very shy in their presence. The others are fine.

    All Nannostomus spp. are legal imports to Australia as of 20/10/2013:

    The IUCN Red List reports Nannostomus beckfordi as a species which has not yet been assessed at 20/10/2013:

    It is very important not to release any aquarium specimens into our waterways. Any that are not sold or re-homed/ given away, can often be re-sold to aquarium stores. If they are homed in ponds, care should be taken that they cannot escape in run-off into our waterways. Even if fish are native & local they should not be moved from one waterway to another, as this can transfer disease. If they are not local fish, they can both spread disease and either out-compete or eat local fish, shrimp & plants, causing their demise.

    They are a good fish for beginners.
