Kind of a goofy question, but I don't know who else to ask! I teach at a parochial school, and the teachers move throughout the day, not the students. My "homeroom" is the 8th grade, so the 8th grade kids are in my classroom all day long, except for lunch and gym. The room is white cinder block--- boooring! I try to dress it up with bright bulletin boards, plants, and lots of posters, but I've been thinking about adding a small fish tank as well. Nothing elaborate, just some small goldfish and maybe a few other freshwater fish. My question is, how time consuming would that be? I'm hoping to hear from others who have fish tanks as well. I'm not worried about the food issue- they make those food pellets that last for a whole weekend, or "vacation" pellets that last a couple weeks (so the fish can eat during Christmas break, spring break, etc.). I just don't want to spend 2 hours cleaning the tank each week, and before I purchase anything, I'm just wondering how much maintenance fish actually take. Thanks!
