Food and feeding
Use a quality flake or pellets for the staple diet, Yellowhump eartheaters will also relish treats of blood worms, brine shrimp and chopped earthworms.
South America; Yellowhump eartheaters are found in the river basins in Colombia.
Males tend to be larger than the females and more colourful, they will also develop a nuchal hump when mature.
Yellowhump eartheaters do not actually form pairs but the male will try to court several females at the same time. The female will clean the spawning site and lay her eggs one at a time. The male will then spread his sperm on the rock after the female has scooped up the initial eggs. Further eggs are then laid on the stone and the female will again scoop them up into her mouth, because of this process it is believed that the fertilisation actually takes place in the female’s mouth. The fry should be released after a week and will feed on newly hatched brine shrimp and crushed flake.
The expected life span for Geophagus pellegrini is 10-15 years.
A male should be housed with several females to prevent a solitary female being harassed. Always use a fine substrate in the tank as Geophagus pellegrini love digging through looking for titbits.
