The New Guide to Aquarium Fish 0

When you think about surfacedwelling fishes for the community aquarium, usually the first ones that spring to mind are the hatchetfishes of the family Gasteropelecidae. The two genera usually encountered by the aquarist are Gasteropekcus and Carnegiella. These are easily differentiated as Gasteropekcus is larger (up to 9 cm (3 1/2 in) in the case of Gasteropekcus maculatus) and has an adipose fin, whereas Carnegiella is smaller (4 cm ( 1 1/2 in) in the case of Carnegiella strigata) and lacks an adipose fin.

Regular pond maintenance and water-quality checks help keep diseases away from fish, but illnesses still occur, even in the best-kept ponds. The first sign of a problem may be a fish floating at the surface, by which time it is probably too late for effective treatment. For this reason, it is vital to set up a routine for examining fish; feeding time provides an ideal opportunity to check their appearance and behavior.

Fish are susceptible to a wide range of bacterial, viral, fungal, and parasitic diseases. The artificial conditions in the aquarium tend to concentrate the risk of disease and increase the speed at which illnesses spread, because fish health is strongly influenced by the quality of the environment. Early intervention can head off many of the most common conditions, but, as with humans, prevention is always better than cure.

[Ebook] Encyclopedia of Aquarium & Pond Fish – Directory of Freshwater Fish – Cyprinids – Rasboras

Encyclopedia of Aquarium & Pond Fish 0

The majority of rasboras are shoaling fish, and if they are kept singly in the aquarium, they become shy and nervous. There appears to be some recognition between members of a shoal, since new individuals added to an aquarium containing an established group are unlikely to be accepted readily by the rest of the shoal.

[Ebook] The New Guide to Aquarium Fish – Cypriniformes – Loaches

The New Guide to Aquarium Fish 0

Being bottom-dwelling species, the loaches are either eel-like or have a triangular body crosssection, their flat bellies being in contact with the substrate. Loaches may have very small scales covering all the body; be partially scaled, in which case the scales are missing from the underside; or naked. When you think about it, the absence of some or all of the scales is a very sensible arrangement, because if scales were present on the belly of the fish, they would be dislodged as the fish moved over rocks and sharp gravel, leaving it open to infection.
