Myopathy and steatitis in the common guppy, Poecilia (Lebistes) reticulata (Peters).
There was 1% mortality among female guppies just imported from Southeast Asia. Moribund fish showed discoloration, lethargy and kyphosis. Microscopically, myopathy and steatitis were observed, together with an extensive ceroid storage. These findings are indicative of vitamin E deficiency, and illustrate the risk of using fish of unknown origin in toxicological studies.
