Hi I'm thinking of moving to a different address quite soon. I have a large tank full of tropical fish and would appreciate some advice on how to transport them to my new address without killing them. The tank is a big one and very heavy so it isn't possible to carry it with any amount of water in it. I have moved with coldwater fish before and just put them in a bucket but I'm thinking that the change of temperature wouldn't be good for my tropical fish. :)

Have as much original water as possible for their transport, the more the better. There are also air stones that are battery operated. Use them as well. At the other end very gradually add new water to the tank. Hope the move goes well for you and your fish.

Yeah you can maybe get a large container and put some of water in it to carry separate and then add it back once you get there.

No Help - You're right about taking more of the original water. Didn't think of that - duh! The more of the original water the better.

Is it a short move or a long move?
How long will they be out of their tank?

They will be out of the tank for about 24 hours as I will need to empty the tank move it to the new place fill it back up and let it stand so the water get to the right temp:)

You can use a cooler filled with 3/4 aquarium water and 1/4 fresh clean treated water.
Get a sponge filter that runs off an air pump and get a battery operated air pump.
Float your filters bio-media in the cooler with the fish. This will be either
Bio wheels, bio sponges, etc. If your filter only has debris cartridges, shake all
The dirt and grim off them using aquarium water and float them - only if you have no other bio-media.
Install the sponge filter, hook it to the air pump and run.
Since there will be no heater during this time, keeping a room temp between 74F-76F will insure that the fish do not get too cold.
Do a 10-20% water change if your fish need to stay in there any longer than 24 hours.
When you put your fish back into the aquarium, put the bio media back in the filter as well and don't forget to acclimate your fish to the aquarium.
Good luck with your move, hope it's successful.

Thanks for the advice:)
