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.
The acid test ratio measures the liquidity of a company by showing its ability to pay off its current liabilities with quick assets. If a firm has enough quick assets to cover its total current liabilities, the firm will be able to pay off its obligations without having to sell off any long-term or capital assets.
