Goldfish Bowl
The standard goldfish bowl with it’s bubble shape has been for years the go to home for a new pet goldfish. It’s an iconic image that most people associate with the first time fish owner. It’s small in size, it looks easy to maintain and the common goldfish is inexpensive; perfect for a beginner with no experience. Sure, for the most part this is true but many pet goldfish don’t live as long as they should. The main cause for an untimely death is due to improper care. Two common mistakes include overfeeding and infrequent water changes.

Goldfish Bowls and Why you Should Consider an Upgrade to a Goldfish Aquarium
A small goldfish bowl requires more cleaning and maintenance than a goldfish aquarium tank. Goldfish can grow large and will outgrow a bowl sooner than later. If a pet goldfish owner has the space, a 10 or 20 gallon tank is recommended. By providing enough space and water for a goldfish to grow and cutting down on the frequency of goldfish care and maintenance for the owner, both owner and goldfish will be much happier.

Lol, I’m not sure if this was a joke or a legit question. If it’s brown, I don’t think it’s a goldfish. Umm but take a look at the section on identifying goldfish breeds. I don’t think you need to worry about the germs if you used clean water in the tank you put it into and not used any toilet water. why would anyone put a live fish into the toilet? Good on you for saving it though!
Today, I rescued a fish from the toilet in my dorm. I’m not sure what kind of fish it is. It looks like a goldfish, but i’m not completely sure. Should I worry about any germs that the gold fish may have picked up or anything like that? (how can I even be sure its a goldfish?)
It’s hard to say why and it’s likely not a problem at all. it could be that it doesn’t feel secure and so it’s sticking to the bottom. Do you have decorations for it to hide amongst? Having a few decorations will make if feel safer and this might be enough to get it swimming around
my goldfish only stays on the bottom. why is this.
Sometimes my goldfish don`t feel well so I put him in a glass of water and make the water bowl fresh then I put him back in the bowl.
If your goldfish is always at the surface blowing bubbles, it could be a sign that your water needs more oxygen but if it only does it occasionally, It’s probably nothing to worry about. You can increase oxygen by keep the water temp cool around 70*f, adding an air pump to agitate the water surface or add a few aquatic plants.
Sometimes my goldfish “blows bubbles” at the surface. The bubbles stay at the surface at the edge of the bowl. What are these and why does my goldfish do this?
