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.
Acid Test Ratio. The acid test ratio, sometimes called the quick ratio, is a liquidity ratio that measures a companys ability to pay off its current debts with only quick assets. Quick assets, sometimes called cash equivalents, are current assets that can be quickly and easily converted into cash in the current period.
In finance, the Acid-test or quick ratio or liquidity ratio measures the ability of a company to use its near cash or quick assets to extinguish or retire its current liabilities immediately. Quick assets include those current assets that presumably can be quickly converted to cash at close to their book values. A company with a quick ratio of less than 1 cannot currently fully pay back its current liabilities.
