Will my fish be OK without a heater?

Some fish are able to survive in a bit cooler water. However, there are some fish that are extremely sensitive to temperature, for example angelfish are very sensitive, and I don’t think they would survive. I have had fish such as guppies and neon tetras that were able to survive for a couple days without a heater.

A good range is 76° to 80°F (25° to 27°C). A few species need to be kept several degrees warmer, and some species require temperatures a few degrees cooler. A thermometer is vital. A stick-on type enables you to check the temperature whenever you look at the aquarium.

Should I turn off aquarium heater at night?

Never turn it off. Adjust it so it maintains the tenperature needed for the aquatic life you have and leave it alone. It should turn on and off on it’s own to regulate the water temperature. If it’s not and it stays on making the water too warm it’s broken, replace it.

What fish can survive in cold water?

Cold-water species, such as char, trout, salmon, grayling, and burbot become stressed at high temperatures and are most active in cold water. Because these designations are informal, different authorities may recognize different boundaries in temperature preference between the categories.

Do aquarium heaters use a lot of electricity?

The biggest consumption is used for the lighting system which accounts for approximately 45% of the total bill. Usually the heater comes in second at about 35% of the total cost. Filters commonly run at about 12% while airpumps, etc. account for the remaining 8%. Again this is based on the average aquarium setup.

Do I need bubbles in my fish tank?

Without this agitation, carbon dioxide cannot leave the water and oxygen cannot enter. Aquarium pumps influence agitation by displacing water with air bubbles. Air pumps ensure fish have enough oxygen to breathe regardless of outlying factors, such as medication’s presence in the water or photosynthesizing plant life.

Do I need an air stone if I have a filter?

The answer is an absolute yes, it does not matter whether you have a filter in your aquarium or not, attaching an air stone makes the water circulation much better.

How do I know if my fish tank is low on oxygen?

Signs of Low Oxygen

They will swim less vigorously and even eat less often. As oxygen levels drop further, the fish will begin to show labored breathing and more rapid gill movements as they desperately attempt to get enough oxygen from the water by passing more water over their gills.

Can a fish survive in tap water?

Ordinary tap water is fine for filling up the aquarium as long as you let it sit for several days before adding fish (the chlorine in the tap water will kill the fish).

How can I oxygenate my fish tank without electricity?

Pouring water from a height, manually stirring the water, or performing large water changes, are some ways to quickly increase oxygen in fish tanks. These methods allow more oxygen to dissolve in the water, and release carbon dioxide.

Do air stones add oxygen to water?

Before purchasing an air stone, it’s important to understand what its purpose is. First, they provide oxygen to the water and diffuse large bubbles. In addition, they can reduce the noise created by the filtration system. The reason they’re useful in aquariums is that they’re cheap and easy to use.
