| Coming to a shop near you: The Semaphore tetra |
| 11/01/2010 |
Aquarium Glaser based in Germany are one of the leading importers and wholesalers of rare species and are one of the major suppliers of fish to UK shops. Over the coming months we will be reporting on rare species that they have recently imported and may well be in stock at a shop near you. This week they have imported a rare Tetra, Pterobrycon myrnae (The Semaphore tetra) . The information supplied by Aquarium Glaser is as follows:-It was only twice, 1998 and 2008, that we received the Semaphore Tetra by Thomas Schulz. This fish is restricted to fast running brooks in Costa Rica.
It is a spectacular tetra and luckily absolutely unproblematic and peaceful. It has an internal fertalization and the female is able to store the sperms over a long period. The fish has an extreme sexual dimorphism. Females are plain blue-grey, whereas the males are particulary colourful. Only the males develop the semaphore-like long scales which are responsible for the common name. Moreover the males have longer anal and ventral fins. The females become slightly bigger (up to 55 mm total length) than the males, which stay 10-15 mm smaller. The mating rituals are very interesting to observe. During this the male presents the „semaphore scales“ widely spread. We were able to produce a few offspring from the wild collected fish which will be offered by Aquarium Glaser in very near future. The eggs are attached on substrates by the female.
