Temperature: Wild fish prefer lower temperatures but tank-bred specimens are happy over the range 72 to 77Â°F (22 to 25Â°C). It won't do well if kept in warmer water than this long-term, with the likelihood its lifespan will be reduced considerably. pH: 6.0 to 7.4.

Quick assets, sometimes called cash equivalents, are current assets that can be quickly and easily converted into cash in the current period.
acid test ratio. More stringent than 'current ratio,' it excludes inventories (typically the least liquid of current assets) to concentrate on the more liquid assets of the firm. Usually an acid test ratio of 1.0 or higher is considered satisfactory by lenders and investors. Also called acid ratio or quick ratio.
