Food and feeding

Diamond tetras will accept all foods offered. Use a quality flake for the staple diet but give then treats of blood worms and brine shrimp 2- 3 times per week. They will also need some vegetable matter adding to the tank in the form of spinach or peas.


South America; Diamond tetras are to be found in lake Valencia, Venezuela and its surrounding rivers.


When the females are ripe, they will have fuller bodies and the males will have extended finnage.


Spawning will normally take place at daybreak and the eggs will be scattered over fine leaved plants. The use of Java moss or spawning mops will aid this but remove the parents after spawning or they will attempt to eat the eggs. The fry can be fed on Infusoria initially and after a week they should accept newly hatched brine shrimp or crushed flake.


The expected life span for Moenkhausia pittieri is 3-5 years.

Short description

As with all tetras, Moenkhausia pittieri prefer to be kept in small groups. The tank should be planted but leave open swimming spaces. They prefer soft water but are tolerant of pH ranging from 6-7.
