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

Should I get rid of snails? Snails in the aquarium can be very useful. Many fishkeepers tend to overfeed a little, and this extra food sinks to the bottom and decays, polluting the aquarium water. Snails will happily come and eat up the left overs though - if you have an outbreak of snails you are most likely overfeeding your fish! If you really do want to remove snails, fish like the clown loach, and several puffers will eat them - but do make sure they are compatible with the other fish in your tank
