My dad is actually a fish person himself (though he got out of it because he had to take care of me, hehe). I have learned all of the basic fish care from him. Though when I was seven he had a little community tank. I was intrigued and I helped him maintain the aquarium for a while. I finally asked him if I could get a fish of my own, and he said yes. We went to the store and bought a two gallon bowl, heater, etc and came back with a betta fish.
Who knew that six years later I would still take care of bettas!
