Something weird just happened, and I’m honestly kind of worried. I was cleaning the tank this afternoon, and I noticed that my goldfish, Blubby, has this small bump on his side that wasn't there before. It looks kind of like a growth, and I’m freaking out a bit because I have no idea what it could be. It wasn't there last week—I always check on him when I'm feeding him around this time of day. He’s swimming around and eating like normal, but I just can’t shake the feeling that something’s up. Is this something I should be super worried about, or am I just overthinking it? I really don't have much experience with fish, so any advice would be appreciated!
Appreciate the question — let's unpack this. A growth on your goldfish can certainly be worrying, but let's talk about what might be happening. Goldfish can develop growths for a variety of reasons. It might be something as benign as a wart-like tumor or a cyst. Other possibilities include infections, parasites, or even environmental stressors such as poor water quality.
The first step is to make sure your fish's environment is as healthy as possible. Test the water conditions to ensure the pH levels, ammonia, nitrate, and nitrite levels are all in the safe range. Regular water changes and a good filtration system are crucial for preventing health issues. Feeding your goldfish a balanced diet can also support their immune system.
Keep an eye on the growth. If you notice it getting larger, changing color, or if your fish seems to be acting differently, such as showing signs of distress or lack of appetite, this might indicate something more serious.
For now, monitor the situation closely. If the growth continues to change, or if your goldfish shows other signs of illness, it’s best to consult with a professional. Feel free to book a video consultation with a vet via Dial A Vet for a more detailed analysis and guidance tailored to your fish's needs.
