75 gallon or 90 gallon

[reefwars]

i hate my 90 truth be told i hate all tanks 24" in height its a pita to reach down to the bottom ideally my tank would be 20" high.a
blue tang would be ok as a juvie but it will quickly out grow a 70 or a 90g.they become rather big fish and need lots of swimming room.if you do get one get one as a babie but it will need to be passed on as it gets bigger
