Betta fish are becoming a very popular fish among aquarium enthusiast around the world, but they are still considered a fragile species of fish. They are very sensitive to fluctuations in the water, be it temperature changes or chemical levels (nitrates and ammonia for example). They are also susceptible to different types of parasites. Here are the Top 5 causes of Betta fish diseases and some tips to help you treat ill fish.

   1. There is one very important symptom that almost always signals an illness in betta fish: lethargy. Betta fish that act extremely lethargic or lazy may not be getting enough oxygen into their system for one reason or another and may need you to take action in order to improve their health.

   2. The second most important sign that your Betta may be sick is its coloring. If your fish starts to dull in color or lose some of its vibrancy it usually indicates that something is wrong. If you notice a color change in your fish, it may or may not be a disease, sometimes it can be that your fish is stressed. Stress can play a huge role in the health of your fish, so you'll want to eliminate any stress factors that could be influencing your fish. These can include direct bright light on your fish, too small of a living environment, and any constant loud noises that may be too close to its tank. Now once you think that most stress factors can be ruled out; then you can probably assume that your fish is ill.
