Aquatic plants are used to give the aquarium a natural appearance, oxygenate the water, and provide habitat for fish, especially fry (babies) and for invertebrate species. Some aquarium fish and invertebrates also eat live plants. Recently, there has been a movement in the hobby to use aquatic plants as part of aesthetic aquarium design and aquascaping, spearheaded by Japanese aquarist Takashi Amano. read full article…

Instant Fish was an idea conceived by the Wham-O toy company in the early 1960s.
Instant fish were a species of African killifish that laid eggs in the mud at the start of the dry season. The eggs lay dormant until the rainy season, when the water would cause them to hatch and be able to survive in full rainy season rivers and lakes, rather than the dry creeks of the dry season. Wham-O had the idea of selling chunks of a mud substitute with the eggs inside it. Once this was taken home and put in a suitable container, water would be added and the eggs would hatch. read full article…

Fish are commonly measured in several ways. Taxonomists use the following two measurements for overall fish length:
Standard length (SL) refers to the length of a fish measured from the tip of the snout to the end of the caudal peduncle. This measurement excludes the caudal fin.
Total length (TL) refers to the length from the tip of the snout to the tip of the caudal fin. It is a straight-line measure, not measured over the curve of the body. read full article…
Fish are susceptible to fish diseases just as any other organism. There are hundreds of afflictions that can effect the health of fish. Fish diseases can be refered to as etiology organ/system most severly affected. Communicable disease can easily affect most fishes in the aquarium due to limited volume of water and increased number of fish compared to natural environments. Many diseases in captive fish are avoidable and preventible. Water conditions are important factors. In spite of all precautions, disease episodes may still occur in the aquarium especially when fish face environmental stresses. read full article…
