This phylum can act as ecto and endoparasites in fish and in turn are responsible for many diseases. Observation on cultured samples by using swabbing techniques on the gill surface indicated the presence of ciliated protozoan. The morphological features of the vegetative stage ciliates were kidney shaped and highly motile with 49.12 µm in length, whereas the resting stage of the ciliates was round shape with 38.42 µm in length as shown by light microscopy. Observation on the cell surface by scanning electron microscopy indicated unfamiliar silverline system for ciliates and the resting cyst surface structure was mildly wrinkled. Further specific species identification was verified by conducting Polymerase Chain Reaction (PCR). The ciliate gene in the 18S SSU ribosomal RNA isolated was very similar (99% sequence identity) to </span><em><span class="fontstyle2">Colpoda steinii </span></em><span class="fontstyle0">DNA sequence at GenBank under accession number of KJ607912.1 with 100% query cover.
