Fish are cold blooded animals and rely on the temperature of the water for their heat. There are some fish (Tuna) that are reported to have a method of heating their bodies above ambient temperature by extreme exertion.
give it a blanket, and cuddle it everyday
in their tank
Depends on type of tank you wish to keep, rather more aggressive or community, higher PH or lower, cold or warm, completely fresh or brackish, etc. Your best would be to choose a type of fish you like the best, then research which fish can be with that fish.
Betas are tropical fish and do best in water that is consistently warm, around 78-80°F. Cold water can stress them out and lead to health problems. It's important to keep their tank at a stable temperature to keep them healthy and happy.
Your fish tank may be turning green due to an overgrowth of algae. Algae thrive in environments with excess nutrients, sunlight, and warm temperatures. To prevent this, you can try reducing the amount of light your tank receives, cleaning the tank regularly, and avoiding overfeeding your fish.
TONS... and the other fish in the tank like to eat the eggs so is you want them to hatch then put them in another tank and keep the water warm.
No, it is not safe to add warm water to a fish tank as sudden changes in temperature can stress or harm the fish. It is important to gradually adjust the water temperature to match that of the tank to avoid any negative effects on the fish.
They do not HAVE to be warm. I keep mine under a light built into the lid to keep him warm. It is nice to keep your fish warm. It is very pleasant in winter. I would suggest a warmer.
its for tropical fish and salt water fish. they need to have warm water to survive cause were they live is really warm waters
That all depends on how warm the area is where you wish to keep the tank. If the tank will need a heater/thermostat unit then that would be the main physical limiting factor. The unit must go completely under water. I would remind you however that the smaller the tank the harder it is to keep fish in it successfully. The basic rule for keeping fish is 1 gal (4.25ltrs) of water is needed for 1" (2.5cm) of fish.
Usually there is a heater that warms the tank on purpose.
no tropical fish need warm water
