They are sub tropical in their requirements and do not do well below 60F. If there is a chance of their water going below this their water should be heated.
Blood parrots are tropical fish, yes they do need heaters.
Yes every fish but gold need a heater. Keep the temperature 76 to 80 degrees fahrenhei
Paradise fish should never be in a situation where it meets a Goldfish. The Paradise fish is a tropical fish and needs its water over 65F. The Goldfish is a coldwater fish and needs its water below 65F. Ergo they need different temperatures and so should not be kept together. Thanks for you help!! :)
There are several reasons why housing these two very different types of fish together would be a bad idea. First off, paradise fish need to be housed in warm water and goldfish need to be housed in coldwater, there is no way to compromise here without harming your fish's health and certainly preventing them from thriving. Along with not having proper water temperatures there would also probably be quite a big size difference and a number of aggression issues caused by either of the fish. The paradise fish will probably be able to eat faster then the goldfish thus causing the goldfish to starve, also paradise fish and goldfish have different nutrient requirements and need to be fed different types of food(which you can assume is hard to do if the paradise fish keeps eating the food intended for the goldfish).
yes guppies are hot watered fish so they need a heater and a filter also to be feed unlike an alge eater
No they CANT have a heater because the temp of their water cant go over 75 f. They arnot tropical fish so they cant have a tank temp. that is higher than that.
This depends entirely on what type of fish you mean, and what the ambient temperature of the place where the fish being kept is. Goldfish, for example, do not need a heater. They are best kept at room temperature. Tropical freshwater fish, which need 77-82F generally, will need a heater within a few days if the ambient room temperature is below about 73F. Usually tropical fish are able to tolerate somewhat cooler temperatures (70-75F) than they need for a time, but it leads to stress which eventually leads to disease. Fungal infections are common in fish kept in water which is too cold.
You can but it will need to be a plastic or acrylic heater, inline heater, or have a heater guard over it, otherwise it may melt the acrylic. For smaller tanks small mini heaters are available that would work just fine. Check out www.bigalsonline.com they will have what you need.
The best candidates are Betta fish and Paradise Gouramis
No
yes but it would need a heater as they are both tropical fish and you would need to change the water alot.
If the temperature is around 20 degrees (Celcius) probably not. But for a five GALLON fish tank, probably.
