its kool but at petco they ush have water test kits. or petsmart of whever u buy fish try posting your problems in cold water part of the fourm ill post the link.
it gets easyer i promise hahah http://www.monsterfishkeepers.com/f...ater-Temperate-and-North-American-Native-Fish here it is. See when you click fourm there is diffrent sections for diffrent types of fish. Say it you click bottom dwelers there then it narrows down. then you have the option of catfish or stingrays. so if you have a catfish or want to learn about catfish you click the catfish and read though others threads or post your own. if you have a stingray or want to learn about them you click stingray. anoter example if you go to fourms and click acient fish it narrows down to Arrowana's, lungfish ect. you click on what you have or want to learn about. its also goodways to figure out if you can put the fish in your tank.
