Glassfish aquarium2/3/2024 The fry are much larger than one would expect-they can eat microworms or vinegar eels immediately, and will also pick at infusoria in the tank. Once the adults are out of the tank, the fry will be able to survive. They are too small to be netted, so either collect and move the eggs to a hatching tank, or alternatively, move the adults to a different tank after a few days worth of eggs have been laid. The adults are very proficient fry predators, however, so steps will have to be taken to save the fry. Incubation is short and the remarkably large fry will appear three or four days after the eggs are laid. The eggs are non-adhesive and will scatter into mats of plants such as Java moss, or even into a yarn spawning mop placed on the bottom of the tank. ![]() They probably breed at night, because the females will be thin again by morning, waiting for another feeding to start making new eggs. The addition of food equals eggs: a morning meal of baby brine shrimp or microworms, which are visible in the stomach of the fish, will create the day’s load of eggs that evening. Females will produce three to eight relatively large eggs that can be seen in the abdomen as they develop. A temperature between 72° and 80☏ is acceptable.īreeding occurs daily. Power filters are a poor choice, since the fish can be sucked into the intake tube. Filtration should be gentle, so a small air-driven sponge filter will suffice. Very small tanks are appropriate, and a breeding group of 10 to 20 adults can be easily maintained in a 2½-gallon tank. Water chemistry in the aquarium is not critical, so long as extremes are avoided. Ideally, they are best kept in a species-only tank. The species is not hard to accommodate in the aquarium-the only important thing is to avoid housing them with fish that might consider them an easy meal, which could be just about any other fish. The water chemistry in the river is moderately soft at 100 to 200 ppm total dissolved solids, with a KH less than 3, and a neutral to slightly alkaline pH. There is a hypothesis that the species produces a sound with a specific set of bones to help mates find one another in the turbid water. The water in their natural habitat is usually muddy, making these fish even harder to see. translucida is found among the roots of floating plants and is a micro-predator that targets very small invertebrate organisms for food about the largest food that an adult can handle is live Artemia nauplii. The fish also lack scales, barbels, and a lateral line.ĭ. Those dots are so small, however, that seeing them without the aid of macro photography is difficult. translucida is almost completely transparent (hence the common name micro glassfish) except for its eye and some distinctive black spots on the lower half of its body. There are currently two identified species in the genus Danionella, along with a few undescribed types. ![]() This fish-Danionella translucida Roberts 1986-grows to just over a centimeter in length, and is less than a millimeter thick. In the mid 1980s, a very small fish was described from the Irrawaddy (Ayeyarwady) River Basin, so small that it is considered to be one of the tiniest vertebrate organisms on the planet. This country has also produced many of the very small fish of interest to nano-tank hobbyists, including Microrasbora erythromicron Annadale 1918 and Indostomus paradoxus Prashad & Mukerji 1929. ![]() Recent discoveries include the celestial pearl danio (previously known as the galaxy rasbora) Celestichthys margaritatus Roberts 2007 and the rose danio Danio roseus Fang & Kottelat 2000. The country of Burma (also known as Myanmar) has become one of the hotbeds of new aquarium fish discovery. We have glass aquariums suitable for freshwater fish and marine life.Danionella translucida: A Micro GlassfishĬalling them tiny would be an understatement! Learn the origins and breeding habits of one of the smallest vertebrate organisms on the planet. However, if you are setting up a very large tank - 500 gallons or more - or you are interested in a tank that is not rectangular in shape, you will probably want to consider acrylic. So, if you want a traditional rectangular medium-sized aquarium, if you don't want to mess with the scratches, and you are not worried about sharp objects shattering the tank, then glass aquarium will be the right choice for you, plus it will save you some cash. Also, when glass is curved, it has a tendency to bend light, making things on the other side of the curved glass appear larger or smaller than they really are. Because of this, it is difficult to make fish tanks from glass that are not rectangular in shape. However, glass is relatively rigid and brittle. The glass in a new tank will match that in an old tank. It is very difficult to scratch. Glass maintains its clarity over time. Glass is a traditional material for constructing aquariums.
