How to Take Care of a Goldfish
Contrary to popular belief, taking care of a goldfish is not care free. The relatively inexpensive price tag of a common goldfish would suggest it’s a fish for beginners but it’s usually consider a fish for novice fish owners. That being said, a beginner can take care of a goldfish if they first know a little bit about the nature of a goldfish and are willing to buy the appropriate goldfish accessories. To properly take care of a goldfish, the beginner will need to obtain the following goldfish accessories (at minimum).

- 10 gallon goldfish aquarium
- Hood cover
- Aquarium filter
- Filter media for beneficial bacteria to grow
- One to two inch layer of aquarium gravel
- Aquarium Air Pump
- Yes, even a few aquarium decorations
- A water dechlorinator that removes both chlorine and chloramine
Here is how you put the aquarium setup together.

That green water sounds like an algae bloom. This means you have too much nitrogen in the water. A water change is a good start but make sure you remove excess food and waste from the gravel substrate. You might also want to but a few live plants. Live plants will use up the nitrogen and take it away from the algae…Your last options is to get a chemical to remove the algae but it’s never a good long term option imo.
