There is probably no other freshwater fish that can show such a poisonous green as body coloration as the about 4-5 cm long ground tetra Ammocryptocharax elegans, which we were able to import in small numbers from the Orinoco darinage (Colombia/Venezuela).
However, the animals have an extreme color change ability and if they sense danger, they are camouflaged brown in a flash. You should keep the animals in planted aquariums, because only if they can sit on plants, they stay permanently green – this has been found out in field studies.
For our customers: the fish have code 203753 on our stock list. Please note that we only supply to wholesalers.
