It is used to regulate the temperature of the water
Cuz it is used to the small tank
yes because there used to the tank and they become nocturnal
A filter...
It will either have to get used to it or die.
I wouldn't recommend using an all-glass tank for reptiles. Any heat source, and thermostat you use, would have to work 'overtime' to maintain the temperature within the tank. this is because 90 percent of the heat generated would simply escape through the glass.
It would depend on the size of the tank, and what comes with it.
How long does it take for a oscar to get used to a new tank
I would not advise it.
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.
To warm up fish tank water effectively and safely, use a reliable aquarium heater with a built-in thermostat. Set the heater to the desired temperature gradually to avoid shocking the fish. Monitor the water temperature regularly to ensure it stays within the appropriate range for your fish species.
The octopus escaped its tank by squeezing through a small gap in the lid and then used its flexible body to reach the fish in a nearby tank.
Fish can disappear in a fish tank due to hiding in decorations or plants, being eaten by other fish, or jumping out of the tank.
