If I were you, seeing as it is college time. I would get something colorful, very easy, and hardy that is not demanding. If after a year all is still well, you could look at swapping out.
Something like:
16 neons/cardinals
8 bronze/peppered/panda cories
bristlenose pleco (otos need a mature established tank to survive not even thrive)
Or perhaps:
pair of rams
10 glowlight tetras
6 cories
bristlenose
Serpae tetras make a great colorful and active addition.
Celestial danios are also a great little, colorful fish.
