In determining if the tank is large enough for fish, some people think the length is more critical than total gallons because the fish needs the room to swim back and forth. so even though I have close to 70 gallons (plus sump), it's still only 3 feet long. So I'm wondering if people had experience one-way-or-another. I.E. is a 3 foot tank too short for either foxface or Kole tang (regardless of total gallons).

I'm thinking probably foxface + starry blenny. or foxface + dwarf lion - existing fish.

BTW, I found a cleaner shrimp in the refugium that has been MIA for a couple months. crazy considering I was doing major cleaning it out a week ago without seeing it!
