very rarely do jardinis get drop eye and nobody knows for certain why silvers get drop eye but i am not gonna go into that right now as for the 140 gallon it is not going to be enough double it and you will be ok or at least 200 gallons they can get over two feet long what is the footprint of the 180 their is no such thing as a golden jardini as me and plenty of other members have told you time and time again so drop that one
