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.
One way to test the strength of a companyâs current assets is to evaluate the acid-test ratio. The acid-test ratio is also known as the quick ratio and it conducts a more thorough test of a companyâs ability to pay its short term debts by excluding inventory and prepaid expenses from the calculation. Thus, only quick assets are included in the calculation.
