They don't move much so a big tank is not a must until bigger but they are slow growing so upgrades would be few and far between.

They can get around 2 feet. In a shipment at a lfs. I had a 16 inched an he was very active and interactive. Was in a 75 and he used almost every inch pretty active contrary to marbled gobies that look very similar

I have one currently in a 40 and have been trying to decide if I should upgrade this summer. He's 11" now and does swim around, but I would call him an active fish. I currently have 2 HOB Marineland penguin 200 's. Also, the last few times I have checked the water, everything looked pretty good (being no traceable amount of nitrite or nitrate and app. .05 ppm ammonia)
