Celebes Halfbeak (5 CM)

Description

The Celebes Halfbeak inhabits the freshwaters of the southern half of the island of Sulawesi (formerly known as Celebes). Here they inhabit shallow running water, taking insects from the water’s surface. The aquarium should be sited in a quiet area and have as large a surface area as possible due to the fact this species can be a little skittish; indeed, it is very important that it is given adequate space so as not to damage the delicate mouth parts on the aquarium glass if it suddenly swims at speed. Tall tangles of driftwood and dense planting, including plenty of surface cover from floating species will help to feel these fish feel more secure. Filtration should be efficient, with moderate water movement and some quieter resting areas out of the current. Small partial water changes will help to keep nitrate to a minimum. Celebes Halfbeaks are best kept in groups, comprised of either a single male with several females, or, in more spacious quarters with ample visual barriers, larger mixed groups containing at least 6 males. The latter will help to spread any territorial aggression amongst the group of males. They are peaceful towards other species and tankmates should be of similar size and temperament. Good companions could include other livebearers, hardy Corydoras spp., Kribensis, rainbowfish, clown plecs etc. Avoid keeping with any tiny fish or fry, as these may be eaten, and likewise, do not house with boisterous species which may intimidate the halfbeaks. Ensure that the tank has tight fitting coverslides, as these fish are expert jumpers. Interestingly, Celebes Halfbeaks develop a black fleshy lobe that hangs down and curves back from the end of lower jaw. It is not clear what purpose this serves. There are two geographical colour variants of this species, one with black fins and one with red fins.
