Hardy Fish

Hardy fish is a term which refers to any fish which is easy to maintain in home aquaria due to their ability to adapt to a wide range of water parameters. Such fish are good starter fish and ideal for 'cycling' your aquarium (i.e. reducing ammonia and nitrites to effectively zero.)

Examples of hardy freshwater fish include Poecilids such as the guppy, molly and platy, most species of Corydoras and some tetras. Generally, fish are hardy only when they have been tank-bred, since wild-caught fish may take many generations to adapt to life in captivity.

Famous quotes containing the words hardy and/or fish:

“A whole village-full of sensuous emotion, scattered abroad all the year long, surged here in a focus for an hour. The forty hearts of those waving couples were beating as they had not done since, twelve months before, they had come together in similar jollity. For the time Paganism was revived in their hearts, the pride of life was all in all, and they adored none other than themselves.”
—Thomas Hardy (1840–1928)

“Until they saw, over the mists
of Venus, two fish creatures stop
on spangled legs and crawl
from the belly of the sea.
And from the planet park
they heard the new fruit drop.”
—Anne Sexton (1928–1974)
