The remaining fish has now started acting a bit strange. It seems like it is "pacing" the fish tank. What could this be? Should I buy another fish to put in the tank with it, or would that cause problems with the original fish?

There could be a number of reasons your other fish died. From an ammonia spike, or an internal problem not seen.

However if your last fish is acting strange, something with the tank is not right. Have you tested your water? You need to test for Ammonia, nitrates and PH on a regular basis.

Before you add additional fish, you need to know what is wrong with the tank. Gold fish as well need lots of dissolved oxygen. This can only enter the water by means of movement of water against air.

Since I do not know the size of your tank, nor the type of your gold fish, positivly saying much more would be difficult. The water needs tested first. Repost or feel free to email me with your findings and we can go from there.

Also, when was the last time you cleaned the tank? Water changes are the best for removing things like ammonia.

First of all, how big is your tank? Goldfish get quite large, and so need plenty of space to grow and swim. Another issue is: did you let the tank age properly before adding fish. If you added these fish in a small tank, such as a 10 gallon, the waste may have added up too fast for the good bacteria to handle, causing the water to become toxic, and therefore killing your fish. If things started out well for a while and then the fish died, were you making regular water changes? Goldies tend to be very dirty fish, producing a lot of waste, so at least 25% of the water needs to be changed every week, regardless of the filtration present. In any case, look at these issues before adding another fish and see if they apply. Happy fishkeeping!!!

Goldfish are extremely hardy fish and it takes a lot to kill them. I suspect you have high levels of ammonia and nitrite. It would help to know the readings on those 2 along with pH and also the tank size, type filter and water temperature.

Do a test of the water and if nothing is there then get another fish to keep it company. How would you like no one to be with. poor fish:( You could ask the pet shop and see what they say, hope your fish is going to be ok

Goldfish are somewhat social creatures, but a tank mate is not needed. Depending on the size of your tank, it may not be a good idea based on the size of the fish either. A single fancy goldfish really needs 15-20 gallons to be at home.
