has anyone had any experience with the eclipse fish tanks? i would like to buy an eclipse 12 for my college dorm( or i may have to settle for a 6) because let's face it, it's just not practical to go carting around my 20 gallon. so, are they any good? would you reccomend them? they look efficient and strurdy enough and they come with a biowheel, always a plus. thank you!
