Why is my betta hiding by the heater?

The reason this happens is that they don’t feel safe. In the wild, betta fish can quickly become prey to bigger fish, so they prefer being in areas with a lot of hiding holes. If your betta feels like he’s too out in the open and he has nowhere to hide then he’s going to stick to his same hiding place all the time.

Why is my fish behind the heater?

This is because he’s a tropical fish and is feeling cold, needing to be near the heater to feel the warmth. It is likely that the heater is not performing efficiently to warm the entire aquarium evenly. The water temperature should be 24-28 degrees Celsius.

Are heaters bad for betta fish?

Since Bettas are typically in tropical conditions year-round, they absolutely should have a heater to keep them warm. The shallow canals and ponds they live in can change in temperature quickly so Bettas are a lot more tolerant to cold than most tropical fish.

Why does my betta fish hide behind the filter?

If you see your betta hiding away behind the filter intake or under the outtake even though he has plenty of other hiding places at his disposal, it could be that there’s a problem with the water quality in the tank. Fresher water comes out of the filter unit, and that’s probably why your fish is hanging around there.

Where do you put a betta hammock?

Instructions on most hammocks recommend that you place it ¾ inches (2 cm) below the surface of your aquarium. Really, you can place it at any height. Experiment. You might find that your betta is just as happy chilling in his hammock halfway down your aquarium.

Can fish get burned by heater?

Yes, aquarium heaters can burn fish, though it’s at best a rare occurrence, and more a case of proximity than design.

How do you know if your betta fish is in shock?

The most common sign of temperature shock is lethargy. Fish are cold-blooded, so unlike mammals who generate their own heat, they can only absorb warmth from the water. When the water is too cold to do this, they’ll often stop moving.

What temp do Bettas like?

75-80 degrees Fahrenheit
The temperature should be kept at 75-80 degrees Fahrenheit. Colder water can kill the betta, as the betta’s immune system will slow and make them susceptible to disease. Hotter water can make them uncomfortable and age quickly, as their metabolism will increase.
