This striking fish can grow a foot in height and therefore demands a tall aquarium. Many fish pictured on the internet labeled as altum are actually scalare. Once you see true altums in person, there is no mistaking them. Stripes that are a bit more brown than black and reddish highlights throughout the fish are true indicators. They are also much taller profiles than scalare. Water conditions are critical for this fish to thrive. It has only rarely been bred in the aquarium.
Pronunciation: Refer to our Pronunciation Key for an explanation of the phonetic symbols.
Habitat: This is the primary location where the cichlid is found and is a generalization. This does not mean a fish cannot be found in other habitats.
Diet: Many cichlids specialize in eating one type of food; notwithstanding, some of these specialized feeders are flexible and can be opportunistic feeders.
Temperament: This describes the overall demeanor of a cichlid toward other tankmates that are of a different species. Consider that there is variability in temperament due to various factors, including aquarium size, tankmates of similar appearance, stocking levels, and order of introduction. There may even be some variability among individual specimens.
Conspecific Temperament: This describes the overall demeanor of a cichlid toward other tank- mates of the same species. Consider that there is variability in temperament due to such factors as aquarium size, stocking levels and order of introduction. There may even be some variability among individual specimens.
Maximum Size: This is in regards to total length (including the tail) of typical aquarium specimens. Wild specimens may not attain this size, or may in fact grow larger than aquarium raised individuals due to various factors. Also consider that this is the typical maximum size and there are exceptional individuals that will exceed it.
