Prior to decription this species was known as A. sp. ‘großmaul’ or ‘bigmouth’, and it has also been assigned the code A190 under the DATZ system.

The genus Apistogramma is among the most speciose of South American cichlid genera with around 70 species valid at present but many more awaiting description. In addition many species exist in two or more geographical colour forms which may or may not turn out to be distinct in the future. Hobbyists tend to label these with collection data if available in order to avoid mixing them and the potential of hybridisation.

This species is also known by the alternative vernacular names 'blue panda cichlid', 'blue sky dwarf cichlid and 'azure cichlid' as well as the confusing trade name A.sp. 'pandurini'. It has also been assigned the 'A' number A183 under the DATZ system with possibly conspecific, related forms similarly numbered A184 or A185 depending on locality.

It can be distinguished from similar-looking species by the length of the lower jaw which characte…

Member species have also been organised into a series of species lineages, sublineages, complexes and groups by authors in order to better separate them.

In its natural waters, females have been observed caring for mixed broods containing both their own fry and those of another cichlid, Amphilophus bussingi. It is unknown if these are mixed by accident (as the two species have also been recorded tending broods in close proximity to one another) or if this represents an adaptive behaviour to increase numbers in a brood and therefore decrease the chance of predation.

Apistogrammas are identified by the use of "A numbers"in a similar fashion to the "L number" system used to identify loricariids. Apistogramma brevis is identified as A168. Additionally, apistos are also grouped into type families and this species is the species type of the brevis group.

Unlike some apistogramma species, a. brevis occurs only in a relatively small range and has not been found outside this.

Localities known in the hobby include ‘Pastaza’, ‘Putumayo’, ‘Requena’, ‘Río Nanay’, ‘Rio Napo’, ‘Maniti’, ‘Momón’, ‘Río Tigre’, ‘Río Ampiyacu’, ‘Shishita’, ‘Shushupi’, ‘Yavari’, ‘Tefé’, ‘Manaquiri’, ‘Lago do Januari’, ‘Mamori’ (often misspelled ‘Mamuri’), ‘Careiro’, ‘Manacapuru’, ‘Juruá’, ‘Curuaí’, and ‘Purutu’ though we’ve been unable to find anywhere matching the latter name within the species’ known distribution, and in fact several of these names are applied incorrectly on a regular basis.

This is the type species of the genus Aequidens and has the widest distribution of any member species. It exists in various colour forms depending on locality with variants from Ecuador and Peru being particularly sought after since they develop striking red (Ecuador) or orange (Peru) colouration on the lower part of the jaw, head and anterior portion of the belly whereas those from Brazil tend to have an overall grey/blue/green colouration, for example.

Despite its type status it's long…

A. calobrensis is not as common in the hobby as some other species in the genus (most notably A. citrinellus). It was considered a member of the genus Cichlasoma for some time, before being restored to its original position in Amphilophus. However it exhibits several characteristics that seem to set it apart from its congeners. As a result many experts believe it will probably be moved into a newly-erected genus at some point in the future. You may also see it listed as a member of Astatheros oc…

Butis spp. are largely nocturnal ambush predators with cryptic patterning to help them blend in with their surroundings. They can also lighten and darken their body colouration to an extent, have a habit of aligning themselves with solid surfaces whether horizontal, vertical, or inverted, and often swim in an upside-down position.

The genus is usually included in the family Eleotridae of which members are often referred to…
