Description

<p>We investigated the diatom flora attached to the inner walls of indoor medaka breeding tanks. Such diatoms are troublesome for the breeder, because they ruin the appearance of the tank and take time to clean. A total of 62 species belonging to 25 genera were identified in the 50 tanks surveyed. In each of the tanks, 0–17 diatom species belonging to 0–11 genera were found. Most of the diatoms were circumneutral to alkaliphilous species, but some acidophilous species were also found in some tanks. Gomphonema was the genus with the highest number of species found, with 11. Cocconeis lineata was the most frequent species, as it appeared in 42% of the surveyed tanks. This study will provide basic information on the diatoms that appear in aquariums.</p>
