Have you already experience one day looking at your tank and seeing your fish sick? It is such a bad feeling and gives off a sense of urgency especially if you are a newbie in the hobby and does not know that to do. Thinking that a sick fish can harm other fish and make them sick is the worst. Stay calm because we will tackle some of the most common treatments for these diseases in your fish tank.
Are you noticing any grayish color, cotton like thing sticking on the gills or skin of your fish? This is most likely may have been a fungal infection. This is due to decaying matters inside your fish tank. It can be easily cured with simple medications which you can buy at your local fish stores. Just make sure next time to regularly clean the water inside your tank.
Parasites like flukes normally attack the gills or skin of the fish. You would notice if the fish is affected if it constantly rubs itself to the walls or ornaments inside the tank. You would also notice a cloudy appearance in the fish's skin. This is mainly caused by bad water quality inside the tank. You should treat this as soon as possible because flukes multiply fast.
Another common parasite attack is what you call an Ich or White Spot. This is so called because a symptom of this is that fish will get little white spots in them. This is primarily due to poor water quality and if the fish is stressed out. Like any other disease, you can easily treat this, just be vigilant on symptoms and keep the water clean.
Another easy case to see is fin rot. The fins are split in a ragged fashion. This is brought about by poor water quality and stressful state of the fish. Again, this can easily be treated with medication, but you need to treat this immediately.
Always remember that like any other disease or sickness, prevention is better than cure. Regularly check the conditions of the water inside the tank. Do not just admire the beauty of the fish; also check any irregularities with them. There you have it. I hope this helps and that your fish tank and fish are all well.
