What is the difference between cold water fish and warm water fish?
What are the differences between cold water and tropical fish? A “cold water” fish doesn’t specifically require its water to be heated. On the flip side, “tropical” or “warm water” fish need their water to be at an optimum temperature to be healthy and comfortable.
What’s considered cold water fish?
Cold water fish include salmon, tuna, mackerel, herring, trout, anchovies and other species. Some types of fish, such as white tuna, yellowfin tuna, Spanish mackerel and halibut, have moderate mercury levels and should be consumed no more than once a week (especially if you’re pregnant or breastfeeding).
Which is better tropical or cold water fish?

Can cold water fish live in warm water?
Coldwater fish in terms of the aquarium trade refers to any fish species that prefer cooler water temperatures. The main take away message is that cold water fish like cooler waters compared to their tropical fish counterparts. Typically, these fish can survive at even lower temperatures for a period of time.
Is 27 degrees OK for tropical fish?
It depends on the species, but in general, tropical fish are most healthy in the range of 75-80°F (24-27°C). Cool water fish do better in temperatures below that, usually between 60° and 75°F (15-24°C), but some of them enjoy water well below 70°F, which is not suitable for any tropical fish.
What is ideal temp for tropical fish?

Can I put 2 heaters in my fish tank?
There are some distinct advantages to having more than one heater in an aquarium. If the room that the aquarium is in is quite cold and the aquarium water temperature drops and a single heater can not raise the temperature, a second heater would help boost the heat produced to help raise the water temperature.
Does an aquarium heater need to be fully submerged?
Submersible aquarium heaters can be fully immersed in the aquarium water. It is important that you keep the heater off of the gravel, as the difference in heat conductivity between the water and the gravel could result in the glass of the heater cracking.
