Guppies prefer a hard-water aquarium with a temperature between 25.5 and 27.8 °C (78 and 82 °F) and salt levels equivalent to one tablespoon per 19 L (5 US gal). [60] They can withstand levels of salinity up to 150% that of normal seawater , [ 61 ] which has led to them being occasionally included in marine tropical community tanks, as well ...
Temperature range pH range Water Hardness Bristlenose pleco, bushynose pleco: Ancistrus spp. The bristlenose genus has at least 59 identified species and many others yet to be named. [16] Males and female both have long "bristles" on their nose, the males having distinctly longer ones. 72-84 F (20-27 C) Adonis pleco, polka dot lyre-tail pleco
In its former natural habitat, the bedrock is limestone, resulting in a hard and alkaline water with a general hardness of 6-10 dGH, while the temporary (carbonate) hardness is usually between 7 and 11°. The pH is around 8, and temperature varies little between the seasons, but ranges between about 70 and 85 °F (20 and 30 °C) between day and ...
Guppies are a common example of feeder fish. Feeder fish is the common name for certain types of small, inexpensive fish commonly fed as live food to other captive animals such as predatory fishes (e.g. aquarium sharks, farmed salmon and tuna) or carnivorous aquarium fish (e.g. oscars, gar, grouper and rays), turtles, crocodilians and other piscivores that naturally hunt in fresh, brackish or ...
Water Cow: Eleotris picta: 17" Violet goby, Dragon goby: Gobioides broussonnetii: 21" Though pet stores often label as "vicious" this fish is actually quite harmless Barred mudskipper: Periophthalmus argentilineatus: 6" This fish requires "land" to crawl out of the water. Atlantic mudskipper: Periophthalmus barbarus: 9"
They are sensitive to low oxygen levels but are otherwise relatively hardy, except that they are intolerant of sudden changes in salinity, pH, hardness, or temperature. Consequently, they must be introduced to a new aquarium gently, and small but frequent water changes are best, so the water chemistry does not change suddenly. [20]
Poecilia wingei is a very colorful guppy species, similar to the fancy guppy often found in pet shops. The species was first collected from Laguna de Patos in Venezuela by Franklyn F. Bond in 1937, and rediscovered by Dr. John Endler in 1975.
Cool-water species, such as smallmouth bass and walleye, can tolerate a wide range of temperatures, but tend to be most abundant in cooler rivers or deeper parts of ponds and lakes, where the temperature is slightly lower than room temperatures. Cold-water species, such as salmonids (e.g. salmon, trout, char, graylings, freshwater whitefishes ...
