I currently have about 6 wrasses and 8 fish total in a jbj 30 (don't ask) lol but I'm upgrading in a few weeks and I don't know what tank size to go with. I like the look of the marineland 65 and the 75 seems kinda short. The 90 is just is a bit much and I don't wanna deal with putting a 100lbs of Rock in it. Keep in mind that I'll only be at my current location for 2yrs.
