How long can my food last in the fridge after a power outage? Experts say it depends on the product, and whether it's in a refrigerator or freezer. Kaitlin Reilly
Generally, minnows breed with the slightest rainfall and within a wide temperature range. Contrary to the long-standing presumptions, climate change poses 'negligible' threat to minnows' reproduction. Minnows are also flexible in attaining pre-spawning fitness, which makes them avoid 'skipped spawning' decisions while facing climatic variabilities.
“The safest way to do this is in the fridge (never do it at room temperature) or using the microwave’s defrost setting. Once food has been defrosted, eat it within 24 hours.”

[3] All minnows have one dorsal fin, ventral fins near the anus, a lateral line system (in most species), and smooth, round cycloid scales. [4]
Vietnamese cardinal minnows do best in a water temperature ranging from 19–23 degrees Celsius. Softer water within the range of 37–142 ppm is also preferable. They are peaceful, though males constantly challenge one another, harmlessly, and do well with a variety of fish, such as cyprinids , catfish , loaches , and tetras .
