Hello. I've just been to the fish store to buy sand, wood, rocks and plants. We bought some plants: 2 anubias nana and 4 other plants but I don't know what species. We just started to cycling but the heater is still taking time and the water is very cold. I'm worried that the plants might die in the cold water but I'm also worried they'll die if kept in the plastic bag too long. Can tropical plants survive in cold water/plastic bag? Thank you.
