It's not just abt d initial setup dat we r talking about. U hv to consider d running cost of d tank. Y make life more difficult if u foresee u will hv problems upkeeping d tank in future? I am always supportive of youngsters keeping fishes as a hobby but u hv to b realistic. Go for something which u can afford n slowly upgrade if u find dat u hv d means of doing so. As working adults we already can feel d impact of maintaining a reef tank let alone a student with no income at all? How abt d parents? D bigger d tank d higher consumption n dats going to add burden to d expenses as well. Young man, in life there r a lot of things to consider when u r going into something n u will know wat I mean as u grow older.
