[i have crabs]

when the time comes i have a pair of suction cups for moving tanks, and ill probably have a ton of salt buckets for water which might be easier to move than something bigger,

with the plumbing sticking out the bottom of the tank, just get a couple chunks of 4x4 to set the tank on. and buy a ton of extra plumbing just in case, cause something always goes wrong with plumbing and it will be when the stores are closed

make lots of extra water to bring cause the water in with the rocks always ends up being kinda gross, and i like the almost see through storage bins you can buy also, something around 20g can still be moved easy enough and then the fish arnt in total darkness for a couple hours
