A variety of goldfish problems will occur while you care for your fish. Careful attention for unusual goldfish behavior can be an early way to detect problems.
Below are reviews of some of the most common problems that occur and relatively simple treatment measures.
What do you do if you realize you accidently overfed your fish? Or accidently dumped a bunch of food in the tank?
If there is any remaining food after 5 minutes of feeding attempt to remove it. If it is floating on the surface use a net to skim it off the top. If it is on the rocks in the bottom use a hose to 'vacuum' it up.
Remove excess food IMMEDIATELY as your water quality will decrease very quickly. This is the number one cause of death for your goldfish.

Is it a problem if my goldfish are changing color?
No. It is normal for a goldfish to change color over time.
A speckled fish will usually lose it's speckles and be a uniform color of red, orange or gold.
Usually the back and belly are the last places to change color.
My goldfish picks up gravel and then spits it out is this unusual goldfish behavior?
This is absolutely normal and nothing to be concerned about. Goldfish are known to be bottom feeders. What they are doing is checking the gravel for food.
