It all depends on the size of the tank. If it is not big enough then they will not grow to full size.

One of the most pervasive ideas in fishkeeping is that fish will only grow to the size of the tank they are kept in. This is not true! Fish do not stop growing because of the size of the tank. They stop growing because the water quality is not good and/or they are not being fed properly. The most important part of keeping fish is water changes. You MUST change 20-25% of the water in your tank EVERY WEEK. This removes ammonia, nitrates and nitrites that stress your fish. Be sure to add a dechlorinator when you add the fresh water.
Fish also excrete hormones into the water. Excess fish means excess hormones. The hormones build up and if there are too many fish, they will all stop growing because they know they are overcrowded. This is also relieved by the water changes.
Some professional breeders have drip systems that continually change the water in their grow out tanks. This allows the babies to reach maximum size in the minimum amount of time. For these people, time is money.
People who specialize in a cichlid called a discus will do 50% water changes EVERY DAY. Two inch discus can sell for $30 each in fish stores and up to hundreds for hard to find color varieties online. A good rule of thumb for regular discus value is $10 per inch of fish (not including the tail).

you MUST get a larger aquaruim now. the irridescent sharks (or pangasius) is a catfish that can grow to 4 feet in length. They need a strong current to swim into as well, or they can die.
This is not a fish for the small aquarium. the answer above about frequent water changes and fish keeping growing so long as the water is good is correct. Keeping pangasius in a small tank is cruel. Get a bigger tank, make sure the water quality is good and do not over feed them.

I agree that it is a misunderstanding about fish growing to the size of the tank.
The reason many never grow to full size is as mentioned. Bad water conditions, and hormones in the water.
Even with proper water changes and food it is hard to determine how long it will take a fish to grow to "full size" There are also many other things that effect the growth of the fish. Temprature of the water, genetics of the fish and lighting length cycle just to name a few more.
The best thing to always do is stock the tank for full adult fish and leave it at that. Then you know for sure you will never have problems.
Remember that in the wild you really have to look for fish. Even using suggested stocking levels we "in reality" overstock tanks even when following suggested stocking levels.

The size of your tank has a lot to do with how large your fish will get. Your sharks won't get very big in something the size of a 10 gallon.

Fish grow according to the size of the tank and number of fish. If they haven't grown at all in two years, you should get a larger tank.
