Food and feeding
Vieja fenestrata are herbivorous in the wild but they also eat insects and invertebrates as well. In the aquarium this diet can be replicated by using cichlid pellets or a quality flake and supplement these with spirulina flake and algae wafers. For meaty foods supply the fish with prawns cockles and mussels.
Central America and North America; Vieja fenestrata are endemic to the waterways of Mexico.
Males are larger than the females with extended dorsal and anal fins. They will also develop a nuchal hump as they mature.
Vieja fenestrata are egg depositors so they will clean a site, normally a flat rock but sometimes they will spawn in a cave, and the eggs will be laid. After 2-3 days the fry should hatch and 4-5 days after that they will be free swimming. Offer the fry newly hatched brine shrimp until they are large enough to accept micro worms and crushed flake.
The expected life span for Vieja fenestrata is 8 years.
Vieja fenestrata is very unpredictable and can turn on its tank mates or partner without any warning. If the female looks like she is getting bullied, remover her from the tank or add a divider and only return her after a few days.
