thanks for the info guys.. i am prety much prepare for the lost. relatively live stock for fresh water are much more expensive compare marine. * my perception after market survey.
but in long run, i notice maintenance cost much more in marine tank.may be triple and yes.. as well the instrument start up.
the size of tank in fresh water easily say minimum is 4 feet and 3 feet sum because average fish size will usually hit 1ft for monster fish keeper . but long run only need to pay for water change and electric bill. i have been visiting (window shop) at Aquamarin to study marine and yes, i started to get poison.
