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.
A measure of a company's ability to meet its short-term obligations using its most liquid assets. It is calculated by subtracting inventories from current assets and dividing the quantity by its current liabilities. A higher acid-test ratio indicates greater short-term financial health. The acid-test ratio is more conservative than the current ratio, which measures much the same thing, because the current ratio excludes the value of inventory. This is because inventory can be less liquid than other current assets.
