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. Definition. The ratio of current assets less inventories to total current liabilities. This ratio is the most stringent measure of how well the company is covering its short-term obligations, since the ratio only considers that part of current assets which can be turned into cash immediately (thus the exclusion of inventories).
