Recently, thanks to a friend, I got a wonderful monograph on livebearers from a British antique shop [1]. Along with a number of otherwise hard to find facts that will warm the systematic zoologist, I found here also an unobtrusive information about the blind livebearer Amblyopsis spelaeus (from Greek: amblys = weak, opis = sight), … Read more

The Prolifera prolifica is the smallest of the 19 species of the extremely interesting genus Poeciliopsis, due to its size (males 10 to 18 mm and females 15 to 30 mm). Moreover, only a few litres of water are really sufficient for breeding. However, it is not its body size that determines whether or not … Read more

It is not known exactly which species we grow.

Kasselmann [2] claims that this species looks different). In fact, the genus Marsilea has more … Read more

Its size makes it ideal for small aquariums, but it can also be used in larger, well-lit tanks. Its root system is only a few millimetres below the substrate. On the surface, … Read more

The condition of the plants was deplorable, the owner of the aquarium shop gave me the cups for a symbolic … Read more
