I think that model ship will teach you how the actual architecture of ships works. All I ever built was plastic ones to see what they looked like. But I've put 22 hours in on redoing my fishroom over the past 3 days, with about 10 hours solid still to go. When it's done, it won't hold a pair of each of the 33,000 plus known fish species on the planet, but we could work on an ark. I don't know how we'd divide the flood into hard and soft water, salt and fresh, etc, but I'll leave the taps on for the refill hose and we'll see what happens.
Moving these tanks on my own has been hard work. I'm sore. Today, I move 2 more 40s and 2 30s. Catch the remove, remove the rocks, move them, redecorate , refill and restock. I won't be able to do this alone again, I reckon, but for now, so far so good. I'll have a big cleanup, then I'll take photos and make a new fishroom thread here.
I'm off to get my eyes tested for new glasses. Sometimes when I work away at projects like this I think I should get my head tested, but I know what the results would be.
