I currently have a 55g in NYC - it's definitely doable. Two comments though:
1) make sure there's somewhere you can connect a RODI filter to the plumbing (i.e. washing machine) - you 100% need one
2) moving will suck; i haven't had to yet but imagine it will add more than $1k to your moving...
I'm wondering how many (if any) more fish you think I can add without overcrowding...
Have a 55G (Red Sea 250 G2) which currently has the following in it:
Bangaii cardinalfish
Tailspot blenny
Royal gramma basslet
Helfrichi firefish
6 line wrasse
Flame hawk
Flame angel
Is that maxed out or...
