selecting and caring for fish  

My family had few pet fish, these includes the different kois which are very colorful,one arwana,and an alligator fish. we have tried also saltwater fishes before,but the problem with that is you have to regularly monitor the salinity, the temperature,and its hard and expensive to have one.We even plenty of marine fish including corals, but we got frustrated because one by one the fish died eventually...

first off what size tank your should start out with some type od damsel or chromis to cycle the tank and then you can buy later and it also depends on what size tank you have

when my husband and i started to own a fish, we were so excited that we buy a 50 gallon aquarium at first. we dont know anything how to take care of fish. my husband bought arwanna and another fresh water fish. on our first attempt, of course our fishes died, maybe because of the water temperature, some say because of the overloaded manures or other say its because of improper cleaning of the tank itself. i must say we've been to to plenty of trials and errors until we slightly perfected how to handle fragile animals.
i must say, our arwanna is already a year old since we bought it and its getting big as the days go on. its very relaxing and rewarding whenever we see our fish swim in his beautiful body with the waves of the water.
