Criticism
Criticism has also been made of placing flowerhorns, which are man-made fish, into fish taxa, which are reserved for the identification of species found in nature. This practice can make identification of similar cichlids difficult. Breeding with pure bloodlines of cichlid species has already occurred in a number of cichlids commonly kept in the hobby, risking loss of genetic material.
Flowerhorn breeding also contributes to the commercial demand for new and different fish, possibly leading to questionable practices, such as breeding for anatomical deformities, as occurred in goldfish breeding.
Flowerhorns have been criticized by some cichlid hobbyists and environmentalists for a number of reasons. Interest in flowerhorns resulted in culling of surplus and deformed fish, some of which were dumped in the wild in Malaysia and Singapore, where they survived and disrupted riverine and pond ecosystems. Like many other cichlids, flowerhorns are aggressive and can breed quickly, competing with and eating native fish.

Famous quotes containing the word criticism:
“The visual is sorely undervalued in modern scholarship. Art history has attained only a fraction of the conceptual sophistication of literary criticism.... Drunk with self-love, criticism has hugely overestimated the centrality of language to western culture. It has failed to see the electrifying sign language of images.”
—Camille Paglia (b. 1947)
“Unless criticism refuses to take itself quite so seriously or at least to permit its readers not to, it will inevitably continue to reflect the finicky canons of the genteel tradition and the depressing pieties of the Culture Religion of Modernism.”
—Leslie Fiedler (b. 1917)
“I am opposed to writing about the private lives of living authors and psychoanalyzing them while they are alive. Criticism is getting all mixed up with a combination of the Junior F.B.I.- men, discards from Freud and Jung and a sort of Columnist peep- hole and missing laundry list school.... Every young English professor sees gold in them dirty sheets now. Imagine what they can do with the soiled sheets of four legal beds by the same writer and you can see why their tongues are slavering.”
—Ernest Hemingway (1899–1961)
