AQUARIUM CARE: Dwarf neon rainbowfish hail from the Mamberamo river system in northern Irian Jaya, Indonesia. This huge river has numerous micro-habitats; M. praecox is thought to prefer shallow areas with submerged plants and driftwood. In the aquarium, this is easily replicated, and floating plants also seem to make this fish more comfortable. Some open water is also important for free-swimming, and as a shoaling fish, it should be kept in a group of at least six individuals.

BREEDING: M. praecox is a typical plant spawning rainbow; eggs are attached to plants, then left to develop with no attention from the parents. Spawning mops can be used instead of plants to allow eggs to be collected and raised in a separate spawning tank. Egg development takes a little over a week, and fry relish newly hatched artemia nauplii.

Fishkeeping Facts and Tips

Give your fish a treat! Flaked fish foods are excellent nutritionally, but most fish really enjoy tucking into live, or frozen live foods. Insect larvae such as bloodworms can be collected in summertime from your water barrel, but it is also very worthwhile to attempt to culture Daphnia or white worms for a free food source absolutely relished by aquarium fish. Frozen bloodworm are almost as good and are widely available, though freeze dried live foods tend not to go down as well. See more on feeding fish
