One of the most abundant Loricariidae species in the Amazon is Loricaria simillima. This Whiptail is found on sandbanks, and the colouration and pattern is very variable. It’s a regular export especially from Peru, and it’s an interesting species to keep in the aquarium.


Name: Loricaria simillima (Regan, 1904)

Trade names: Marbeled Whiptail

Origin: Venezuela, Peru, Ecuador, Brazil, Paraguay, Bolivia

Maximum size: 25 cm / 10”

This is a typical sand-dweller that should be given open space on the bottom of your tank. They are very peaceful, and should not be kept with boisterous and oppressing species that outcompete them for food. They prefer meaty foods, abut should be fed a varied diet of quality dried foods and frozen foods. The cool thing about them is that the males are mouth brooders, so the eggs are cared for by the male who keeps them right underneath his head and torso. They can produce more than 100 eggs per clutch.
