Why does my goldfish keep swimming to the top?

Swim bladder is an illness that affects a fish’s equilibrium and is common in goldfish, causing the fish to float to the top or sink to the bottom, or to float sideways or upside down. Overfeeding might be the cause if your fish’s symptoms occur immediately after feeding and go away in a few hours.

Why do my fish keep coming to the surface?

Lack of oxygen in the water will cause your fish to swim to the surface to breathe; the concentration of dissolved oxygen is highest here. As soon as you notice that most of the fish are gasping for air near the surface, act immediately because this is a clear sign of distress.

Why are my fish suddenly swimming at the surface of the surface?

At some point, they reach a level that overwhelms the nitrogen cycle. The result is usually a sudden ammonia spike. You may want to check water chemistry to confirm ammonia and nitrite are at zero concentration and nitrate is below 40 ppm. Ammonia and nitrite are especially toxic to fish; both compounds burn gills and disrupt immune systems.

Why are my fish coming to the surface to breathe?

An overstocked aquarium—with too many fish polluting the water and competing for the same air supply—can cause low oxygen levels.

What makes fish gasp at the surface of the water?

Ammonia and nitrite are especially toxic to fish; both compounds burn gills and disrupt immune systems. Burned gills in turn make a fish gasp for air at the water surface.

Why does my fish go to the bubbles?

Naturally, these dissolved oxygen levels tend to be higher near the surface, where interaction between air and water takes place. A fish that is not receiving enough oxygen will try to compensate by gravitating toward that area. Similarly, you may notice your fish lingering near the bubbles of your air stones or other bubble-producing décor.

Why does a fish gasp at the surface?

Gasping at the Surface: fish is gasping his mouth at the surface, this is a sign of stress brought on by poor water conditions, usually a lack of oxygen. Appetite: fish is stressed, oftentimes he will not eat.

Why are my fish staying at the top of their tank?

What to do if your fish are staying at the top of their tank 1 Poor water quality. Begin your troubleshooting process by performing a water test to rule out any issues with water quality (such as temperature, ammonia, nitrite, nitrate, hardness, salinity levels or 2 Overcrowding. 3 Lack of aeration. 4 Improper water temperature.
