I'm currently in my last year of college, and here's my two cents...
At home, I have a 29, 54, 75, 125, and 180 gal tanks, which I come home to on the weekends. When I first started college, I thought, "I'm gonna need a fish tank at school, otherwise I'm gonna miss fish too much during the week." So I brought my 10 gal glass set-up. BAD IDEA!!!!
1) you're already gonna have a lot of other crap that you have to worry about when you're moving in, that you don't want the extra burden of a glass 10 gal tank.
2) carrying 10 gallons of water from the nearest water source to fill the thing is a **tch.
3) doing water changes at school when your busy with school work and when you have to carry dirty water to the nearest draining facility is even more of a **tch...
4) the water at colleges will instantly kill fish unless you use lots of water conditioner. They tend to load their water with chemicals, so that nobody gets sick from drinking it...
So, now I just have a 2.5 gal tank. It's glass, so I still have to worry about transporting it and all, but it is sooooo much easier in terms of water and changes and upkeep and what not. Plus, at college, you're gonna have so much other things going on that you're not really going to have time to stare at your fish and enjoy them, and you're not really gonna miss them... My 2.5 gal is a planted tank with ghost shrimp, a mystery snail, and cherry barbs... At one time, I did have a little African dwarf frog in there.
