You will need to set up the aquarium first, before you add any fish into it. Then, you can gradually add a few fish at a time. It is a good rule of thumb to keep only one fish per gallon of water in a tropical fish tank. For example, if you have a twenty gallon fish tank, you should keep no more than twenty fish. If some of these fish are large, you should probably have less than that. Overstocking your aquarium is a sure way to kill your fish. It would be a shame if one day your favorite fish died due to an overstocked fish tank.

Mollies

Mollies area terrific addition to any community fish tank. They are peaceful and easy to care for. Mollies belong to a group of fish know as live bearers. This means that they give birth to live young (as opposed to eggs). So, if you don’t want to breed these fish, you had better stick to males. You can purchase a female if you know they have been kept separate from the males.

Mollies can actually live up to three to five years and grow up to five inches long. Don’t be disappointed, though, if your Mollie doesn’t grow this big or last that long.

However, Mollies are very pretty fish and can be purchased in a huge variety of colors and patterns. From black to red to Dalmatian spotted, these fish are lovely. You can also buy a Lyre Tail Mollie. These are names because their tails look like lyres. This gives them a fancy look.

Bala or Tri Color Shark

Bala, or Tri Color Sharks are silver with black and white fins and can grow up to sixteen inches long. They are quite active fish and will help cleaning up left over food from the bottom of the fish tank. Although they are called sharks, they are quite peaceful and will not try to eat any of your other fish.

Iridescent Shark

The Iridescent Shark can exhibit some unusual behavior. You might want to be prepared for this so that you don’t think that something is wrong.

They will occasionally swim up to the top of the tank for some air. Also, they can be nervous fish and swim around the tank rapidly. If you bang on the fish tank, the Iridescent Shark may get startled and swim around hysterically. They may bang in to the ends of the tank or into other fish or decorations. Once they have finished, they may lie down on their sides and breathe rapidly to calm down. New fish owners may be startled by this behavior, but it is normal.
