Frequently Asked Questions (FAQs)

1. How do you feed cold-water fish?

Between 59 and 68 Degrees. In water between 59 and 68 degrees Fahrenheit, the activities of cold-water fish usually slow down a bit. So do their digestive capacities. Feed the fish one to two times each day, in the amount that the fish are capable of eating within a few minutes.

2. What does a cold-water fish need?

You'll need to buy a filter for your tank, as well as a lid, light, and a pH testing kit. Your cold water fish tank should also include a few plants and decorations, so there's plenty of space for your fish to explore or hide away if they wish.

Add coldwater live plants for a more natural aquarium. Live plants look beautiful, offer places for your fish to hide, and help oxygenate the water in the tank. Some good plant choices for coldwater fish tanks include java moss, Cabomba, and water cabbage.
