Adaptive Molecular Evolution in the Opsin Genes of Rapidly Speciating Cichlid Species [PDF]

Molecular Biology and Evolution, 2005
Cichlid fish inhabit a diverse range of environments that vary in the spectral content of light available for vision. These differences should result in adaptive selective pressure on the genes involved in visual sensitivity, the opsin genes.

Algal dermatitis in cichlids

Journal of the American Veterinary Medical Association, 2002
Three varieties of a popular African cichlid aquarium species, Pseudotropheus zebra, from 2 tropical fish farms in east central Florida were submitted for diagnostic evaluation because of the development of multifocal green lesions. The percentage of infected fish in these populations varied from 5 to 60%.

Cataracts in Cichlid Fish

Journal of the American Veterinary Medical Association, 1981
SUMMARY Bilateral cataracts were detected in a group of aquarium-raised tilapia (Sarotherodon mossam-bicus). Vision impairment was manifested as random swimming into objects, but the fish appeared to function normally otherwise. Most of the lens was opaque, with the outer extent of the cortex and subcapsular region remaining transparent.

The “infantilization” of a cichlid fish

Developmental Psychobiology, 1980
AbstractThis paper reports a rather remarkable phenomenon, which we have termed “infantilization.” Young acaras, 7 to 17 days postspawning age and normally freely swimming, will resume their nesting phase when placed with foster parents' brooding embryos or wrigglers.

Pneumocystectomy in a Midas cichlid

Journal of the American Veterinary Medical Association, 1995
This report illustrates the feasibility of radiography, anesthesia, and coelomic surgery in a pet fish. Pneumocystectomy can improve certain buoyancy disorders in fish.
