Being an avid aquarist can be very satisfying or stressful, depending on the knowledge you have in fish. Knowledge can be very helpful, but not always solve the problem. A book may tell you that a certain type of fish can go with this type of fish, but this is not always the case. First hand experience is the best way to get the hang of being an aquarium hobbies. Fish can act differently for a number of reasons, and even for some unexplainable reasons.

For the most part it is suggested to go by the books and get fish that are compatible. As stated before the books are not always correct, so event if it is said that the fish will be fine together than they may not be. After new fish are added to your tank, keep close attention to the fish for a week or so. If everyone in the tank is happy than you can lessen your watch more and more as time recedes.

If you find a fish that is causing a problem you must first identify the problem. The fish may be attacking all the other fish or attacking a certain group of fish. The case may be that two of the fish are battling it out or one fish does not like a certain other fish. The fish may just be digging or very hyper. Whatever the problem is it can be fixed.

Solving this problem can be easy and done without having to kill the fish. Isolating the fish that has the problem in a different tank for a while is best. If the problems cease in your main tank then the fish cannot be with the other fish in the tank, and is best left alone or maybe only with its own kind.

If a group of fish or a few groups of fish are fighting then the problem may take longer to fix. You can remove the first group of fish from the tank and see if the fish are peaceful without that group. Next move the other group of fish to see if the first group is the problem. The group that is the most troublesome must be removed from the tank.

Using these removal and test techniques are usually the best way to identify the problem. If you still have problems with a fish, the best way to fix it is to keep it in solitude. You could also give the fish away or the fish to someone that might have a better chance with the fish.
