Species Information

Identification	Often you will see fish for sale as Hoplisoma julii but they are actually Hoplisoma trilineatus. So, if you bought as fish as julii, it's almost certainly H. trilineatus from the upper Amazon. The real H. julii will turn up from time to time as although it originates from the upper Parnaiba system in the lower Amazon drainage, it is found in the Rio Para where commercial fish collectors operate. Telling them apart without locality information is actually quite hard as some H. trilineatus can show the spotted head pattern traditionally associated solely with C. julii, C. julii appears also to have a shorter horizontal mid body stripe not reaching half way along the body.
Sexing	Females bigger and fuller bodied.

Temperature	23.0-26.0°C or 73.4-78.8°F (Show species within this range)
Husbandry Information
Feeding	Will readily accepted all prepared foods that reach the bottom of the aquarium such as tablets, granules and larger flakes. Live (or frozen) foods such as bloodworm, white worm, grindal worm (Enchytraeus), Daphnia and Tubifex are readily accepted and good for conditioning groups of fishes for spawning. User data.
Furniture	Ideally substrate should be sand, but rounded gravel is an imperfect alternative. Avoid keeping over rough edged (chipped) gravel, this will increase this risk of damage the fishes barbels when it tries to dig. Substrate should be bordered with driftwood and aquatic plants leaving an open area for them to search for food and swim. The shade provided by overhanging rock work, arching bogwood, tall or floating plants are all that is required to settle these fishes.
Compatibility	A peaceful, shoaling, community fish.
Breeding	Unreported.
Breeding Reports	There are 6 breeding reports, read them all here.
