Before other things come along, what you must always do is to first understand your fish. Find out about the type of aquarium fish you are having, study its behavior, learn about the optimal living condition most suited for the species like pH, temperature, water hardness. Don’t worry, because there are many great handbooks you can find and read about aquarium fish keeping.
Time and Commitment is the core to having a successful aquarium. Draft out the routine plan on what you need to do everyday to monitor the water condition. Be prepared to conduct weekly water change. Spend time to visit aquarium stores and get the best fish supplies. Remember it’s not always the bigger the better but it’s more towards getting the right item. Don’t worry, all these effort and money spent will eventually pays off.
Aquarium Maintenance is also another key factor when it comes to fish care. It is consistency that we are talking about here. Most people were only interested during the initial stage but after a while starts to lose interest. All the fish accessories must be checked to ensure that all are running in tip top condition, things like aquarium filter clogging up is the worst thing that could happen.
Learn from mistakes and improve. There are quite a number of things which cannot be learned just be reading alone. The knowledge can only be grasped by first hand look and experience. Fish disease is the greatest enemy, so learn how to avoid or deal with it.
Finally to sum things up, fish care is all about passion.
