• These fish are bacteria and infusoria upon which the fish will feed.
• To these was added an illustrated work on the infusoria, published in 1786.
• If infusoria are unavailable, commercial prepared foods for egglayer fry may also be used.
• The babies are very small, so feeding infusoria ( protozoa ) is necessary early on.
• It was then that scholars discovered spermatozoa, bacteria, infusoria and the diversity of microscopic life.
• After they are free swimming, they can be fed a finely powdered fish food or infusoria.
• The first mention of cryptomonads appears to have been made by Christian Gottfried Ehrenberg in 1831, while studying Infusoria.
• Feeding fry live foods, such as baby brine shrimp, microworms, infusoria and vinegar eels, is recommended.
• When first hatched, the tiny fry should be fed infusoria, and later, brine shrimp and finely ground flakes.
• Fry eat infusoria ( particularly rotifers ) and " green water " ( single celled algae ) for up to a month.
• Fry can be fed with infusoria, paramecium culture, crushed flakes, and rotifers after they have used all the yolk sack.
• His primary areas of research involved the evolutionary development of flatworms, investigations of infusoria and the development of mammary organs in marsupials.
• He was one of the first to study microorganisms, and established the classification of several groups of animals in addition to the infusoria, including Linnaeus.
• Once the fry hatch and have begun to swim freely, the male is best removed and the fry raised on infusoria or newly hatched brine shrimp.
• In the Austrian sector of the Danube, 5 parasite species are registered : infusoria " Trichodina " sp ., Acanthocephalus lucii ".
• Sometime in the early 1940s he returned to his microscope, producing the first part of what was supposed to be another 4-volume treatise on the infusoria.
• While the fry are likely to develop best if given infusoria as part of their feeding r間ime, it is possible to raise fry to adulthood entirely upon prepared foods.
• At this time, microscopic algae were discovered and reported by a different group of workers ( e . g ., Ehrenberg ) studying the Infusoria ( microscopic organisms ).
• In 1838, at the meeting of the British Association at Newcastle, he was the sole opponent of Christian Gottfried Ehrenberg, who maintained the polygastric nature of certain infusoria.
• O . F . M黮ler ( 1773, 1786 ) described eight species of the genus " Vibrio " ( included in Infusoria ), three of which were spirilliforms.
