We shifted house in december..
I had all my plants (anubias, amazon, argentine, chain, micro swords, twisted val and xmas moss) outside in a transparent bed roller bin thing with aquarium water in it up until last weekend (so that's 3.5 months) when I planted most of them again..
They survived. Looked a bit pale and the roots had grown all funny but they are now back in a tank and seems to have done quite well..
