Do Fish Get Bored? This will help dilute the ammonia that has built-up in the tank over time. Invest in a good filtration system for your tank and make sure to replace the filter media at least once a month.
Treat the water with Tetra AquaSafe Plus Water Conditioner each month to not only eliminate chlorine and neutralize ammonia, but to remove metals such as lead and copper as well. Scrap the bottom of the tank regularly to remove any rotting food or waste material that has collected on the substrate.
Conclusion To conclude, there are 5 main reasons why fish will rub on rocks in an aquarium. We use cookies to ensure that we give you the best experience on our website.

You will often see your fish dart suddenly to the side or bottom of their tank and flatten out like a pancake, allowing their side to touch the substrate. Similar signs are fish who exhibit twitchy swimming or swim in sudden bursts. Some fish will jump out of the water and use the surface tension of the water surface to itch themselves. This is obviously very dangerous if they do not end up back in their tank.
If you do not see your fish actively flashing, you may see the secondary signs. Signs your fish are itchy include missing scales, bruising or trauma to the head and fins. If the trauma is severe enough, your fish may be susceptible to secondary infections and neurologic trauma. If left untreated, flashing fish are likely to get worse and can die from flashing too severely. The most common cause of flashing is a parasitic infestation. The most common parasites in freshwater tanks that cause flashing are Trichodina, monogenean trematodes, also known as flukes, Costia or Icthyobodo , and Chilodonella.
All of these are microscopic parasites and require a veterinarian to diagnose the correct parasite. The encysted stage of Ich is macroscopic but easily confused for fin ray fractures. Primary parasite infections are common in fish tanks with recent additions of new fish or live plants without proper quarantine. However, outbreaks can occur in fish under chronic stress situations, such as poor water quality or overcrowding.
Other symptoms for this condition include gasping for air at the surface of the water and clamped fins. Keep an eye out for these symptoms when diagnosing your fish. Consult your vet if you notice white spots on your fish. This, along with your fish swimming erratically in the aquarium, may mean that your fish have a parasite problem.
Your vet can offer you treatment options for your fish. They can also tell you what steps to take in order to preserve the health of your fish. One step is quarantining your ill fish. Ich is contagious. Separate the affected fish until it recovers. Be sure to keep checking the parameters of the water it is in. It will recover faster if the environment is well-balanced. The infection can be on both their gills and their skin.
You can look out for eyespots on your fish in order to diagnose the illness. An unbalanced environment in the aquarium is mostly responsible for this illness. Therefore, you must regularly check the parameters of the water in your aquarium. Ensure you cycle it properly if you plan on changing the water. A poorly cycled aquarium may cause your fish to experience this sensation.
This is more likely to happen when you change the water in the aquarium or the aquarium itself. Cycling an aquarium entails creating a balanced environment in the aquarium and bringing the ammonia and nitrite levels down to zero. Good bacterium nitrate counteracts the excessive production of ammonia and nitrite. Fish flick and scratch for the same reasons that other animals including humans, they are trying to relieve irritation and dislodge foreign objects from the skin. Different fishes will show many varieties of this behaviour.
Open water shoaling fishes may frequently visit the substrate of the tank and very rapidly rub their flanks against the gravel or sand — blink and you will miss it. Erratic behaviour in fishes may not always indicate a problem with their fish. Interestingly many Corydoras catfishes can often be observed darting up to the water surface incredibly quickly before resuming their bottom-dwelling location. The skin of a fish provides numerous important functions; it is a barrier against the external environment, sealing the internal mileu of the fish and preventing infection by pathogens.
Most notably the skin contains the scales, which form a tough outer armour present on most aquarium and pond fishes. The skin is the site of protective mucous secretion amongst other immune factors, it houses receptors for touch, smell and even taste.
