Type Of Heater

Heaters come in two types: internal and external. Internal heaters are placed inside the tank, while external heaters sit outside of the tank on the floor or on a stand. External heaters are generally easier to use and maintain than internal ones, but they can be more prone to breaking.

When choosing a heater for your black skirt tetra, it is important to consider how much power it needs in order to keep the water at a consistent temperature.

Watt Size

Heaters come in different watt sizes – the higher the watt size, the more powerful the heater will be.

Tank Size

Most tanks up to 30 gallons can use a 150-watt heater without any problems, but if you have a larger tank then you’ll need something with more power. You don’t want to choose a heater that is too powerful for your tank though, as it can be dangerous and could even cause a fire!

When looking for a heater, always make sure to read the description carefully to find out how much power it needs.

Heater Watt Size Guide:

30 gallons or less – use a 150-watt heater

75-125 gallons – use a 500-watt heater

125+ gallons – use 1000+ watt heater

Never Place The Heater Behind A Wall Or Cabinet

If you have a stand, never put the heater against any wall or cabinet that can block airflow around it. If this happens then there could be problems with the heating process, which could severely injure your fish!

Place On Shelf Near Aquarium

What Happens If The Temperature Changes Suddenly?

In some cases, shock can be fatal. It is important to monitor your tank’s temperature so that this doesn’t happen!


It is important to place your heater in an area where it will not be disturbed or bumped into. You should also check behind the tank – some heaters are more powerful than others and may cause damage if they get too hot!

If your fish are constantly swimming to the top of the tank to get air, it is possible that they are suffering from a respiratory problem. This can be caused by many different things, such as poor water quality, stress, or an infection. If you think your fish may have a respiratory problem, take them to a vet immediately!
