![]() ![]() The breeding tank will be bare, having no gravel substrate. ![]() It must be well cleaned beforehand and I use cooking salt as a disinfectant to clean mine. I use a 38 x 18 x 30cm/15 x 7 x 12" tank, but any size up to 60cm/24" will be fine. These fish make a great first-time breeding project and here’s how I do it. The females are larger and fuller in the body, but there are no noticeable colour differences between the genders. AdultsĪdults can be easily sexed, with the males being slimmer and having a slightly sunken belly region. There are silver areas in the belly region and the dorsal and tail can show white tips. The obvious red glowlight stripe runs the full length of the fish’s body, with a basic background of olive to yellow-green. It was also of a different build and coloration - more allied to the Flag tetra (H. The tentative identification was Hyphessobrycon gracilis (Reinhardt) but this was not accepted because Reinhardt’s material was from a different locality. J H P Brymer identified the species on the advice of Dr E Trewevas. Since it was first exported from Guyana to Europe in the 1930s it has certainly played the 'change the name game' to the full. The species name of Hemigramus erythrozonus means 'with a red zone or stripe'. It’s also an ideal challenge for the first-time breeder. It’s excellent for the community aquarium, perfect for the newcomer to the hobby, tolerant of varying water conditions and attractive. Unsurprisingly all are easy to keep, but one species, the Glowlight tetra, has everything going for it. It incorporates the fish that seem to have been around for ever and bred in vast numbers by the fish farmers. However, one group is always found in the dealers’ tanks - the 'bread and butter' stock. Our fish also go through these phases, with new species coming into vogue only to rapidly become yesterday’s choice. I suppose in some ways it’s akin to clothes that come into fashion then fade away, perhaps to dramatically return at a later date. In my many years of fishkeeping there have been a lot of changes in the popularity polls of species. John Rundle explains how he breeds these lovely community fish. Some aquarium fish will drift in and out of fashion, but the Glowlight tetra never seems to go out of style. ![]()
