Taking care of fish is in my blood.
We had a large freshwater fish tank in my house from before I was even born, and my parents taught me how to care for the fish once I was old enough to reach the water pump.
At first I learned the feeding schedules. We had all of that information on a sheet of paper that was laminated and attached to the wall adjacent to the tank. There were several different fish food containers that were to be given at strict intervals to accommodate all of the fish species in our tank. Although I could not have a fish tank while I lived in the dormitories in undergraduate school, I bought one as soon as I got my own apartment. This tank started out small and has only grown in the time since as I have transitioned into bigger living spaces. I own the house I live in now and have two different fish tanks—one freshwater tank and one saltwater. The temperature needs to be regulated in their tanks, especially the saltwater tank. My fish are from marine environments that are warmer than my own, so I use a heater and a digital temperature gauge. I stupidly had the tank under an a/c vent when I first moved into this house and couldn’t figure out why the temperature was fluctuating so much. When I realized that the temperature was dropping whenever the a/c was on, I looked up and saw the solution to my stubborn problem. Now I have the tank on the opposite side of the room so the temperature is more stable in the water.
