As far as picking up a tank and moving it, I've never done it with anything bigger than a 29 gallon. But I have slid a 100 gallon around without emptying it, I dont recommend doing it. Drain at least 25-30% first or you will have 25-30% of the water to clean up off the floor....
I picked a full ten gallon up once and somehow it ripped the skin off my thumb and I proceeded to dump the entire tank onto my couch. Take my advice, drain it. I have slid tanks across hardwood floors though.
Drain the tank man. You are a monster fish keeper aren't u?? We must have to get rid of our lazy butt to make sure all the fish are in clean water. If we would let lazy get to us. All our monster fish would die. Just listern to everyone here and drain it. Good luck.
when i moved my 65g tall about 10ft, i emptied it about 80%, with no gravel or anything, just a few smaller fish, and i moved it with someone on the other end. there wasn't any problem...
ive moved my 55 around a bit by putting a 2x4 against the wall and using another one to "pry" the tank/stand around... my stand is real wood.. would never try it with a sawdust/glue stand...
it can be done.. however not really the best idea...
