Symptoms of an Aquarium That’s Too Hot
Symptom #1: Lack of Movement in the Water
In some cases, fish will stop moving around in the fish tank and are going to stay close to one side. This tends to be near the bottom where it’s coolest in the tank.
If the fish are refusing to head upwards even for food, this means the aquarium is too hot!
You have to make changes to the water conditions or it will become unsustainable for your fish. This is why installing an aquarium chiller or cooling fan is the way to go.
It’s going to make sure everything is regulated regardless of what the temperature is outside. This can be a major time-saver as a fish tank owner when you are busy throughout the day.
Additional signs can include:
- Lack of Swimming
- General Fatigue
- Constant Hiding
When it becomes too hot, the fish are going to go into survival mode. This is a natural reaction to their environment and it’s something that can become problematic after a while.
It’s one thing for the fish tank to be a little bit warm, but when it’s burning hot, the aquarium will become unsustainable.
This is why it’s important to make sure you are keeping tabs on the temperature inside the fish tank at all times.
Symptom #2: Health Issues for Your Fish
When an aquarium is too hot, you are going to start noticing health issues in your fish as well.
These health issues are going to include a variety of things include fatigue, fin rot, and other similar conditions that showcase a physical decline in the fish.
It’s in your best interest to take a temperature reading of the water and make sure your fish’s health isn’t compromised.
There are subtle signs that can begin to show a decline in your fish’s health.
This can include fatigue, an unwillingness to eat, and simply staying to one side of the tank. In some cases, you are going to see the fish “riding the glass,” which is an automatic sign it’s in distress.
Fish will often do this when they are significantly uncomfortable in the fish tank and are trying to find a way out.
Symptom #3: Dying Aquarium Plants
When an aquarium is too hot, you are going to want to look at the aquarium plants.
The plants are going to rely on a stable environment inside the tank and as soon as it’s too hot, they are going to begin to wilt.
Since you know this, you can look at the plants and assess their health.
In a lot of cases, the fish are going to see a decline in health first, but the plants are going to follow too. These plants aren’t designed to handle a lot of heat inside the aquarium, so it makes sense for them to start fading.
Symptom #4: Increased Bubbling
The filter is going to start malfunctioning when the temperature rises too much.
This is why you are going to start noticing a sudden increase in bubbling out of the filtration system. This is an odd sight to see but it can be quite noisy too.
It’s a clear-cut sign that your aquarium is too hot and changes have to be made as soon as possible!
