  <dc:description>&lt;p&gt;&lt;span&gt;&lt;i&gt;Tetrahymena corlissi&lt;/i&gt;, a free-living protozoan, apparently caused the death of large numbers of guppies (&lt;i&gt;Poecilia reticulatus&lt;/i&gt;) and occasionally other fishes, in aquaria and hatcheries at several locations. Apparently the disease occurs when the fish and protozoan populations are both at a high level of density. The signs include white spots and epidermal damage. Histologically, &lt;i&gt;T. corlissi&lt;/i&gt; could be seen in skin, muscle, and viscera; in some there was marked inflammation, in others there was little tissue reaction. A key is presented for the identification of invasive fish ciliates: &lt;i&gt;Chilodonella&lt;/i&gt;, &lt;i&gt;Hemiophrys&lt;/i&gt;, &lt;i&gt;Ichthyophthirius&lt;/i&gt;, &lt;i&gt;Ophryoglena&lt;/i&gt;, and &lt;i&gt;Tetrahymena&lt;/i&gt;.&lt;/span&gt;&lt;/p&gt;</dc:description>
