Short trip, only a few fish
For a short trip, all you really need is finding a trusted pet store, borrow some bigger fish bags from them( 1-2 smaller fish, or one large fish per bag) , put your fish in there. cover the fish just barely with water, just above their dorsal fin. Then let the pet store fill up the bag with oxygen, and close it securely. Put the bags inside a cooler, and off you go. Some pet stores do not have oxygen, like Petsupermarket, so you really need to find one with an oxygen tank. Let them double bag your fish, which is basically another bag over the fish bag, in case one is leaking water. Voila, all set.
Long trip, an enormous number of fish
There is a relatively simple, yet safe, way to go about doing this. You'll need a few things, and they'll be especially helpful if the trip is a longer one.
"Ingredients list":
- 1 20 gl new garbage container with lid (or anything bigger than 15 gl, and I usually use 30 gl)
- batterie operated airpumps (sold at most petstores), one for each container, and one for the filter
- regular airpump (for the times that you are in the hotel/with family)
- 1 bottle of Prime (or any other ammonia remover)
- python for water changes (or a few extra smaller buckets, never been used for cleaning before!)
- one plastic container to fit the filter in
- test kits to test for ammonia during trip
- aquarium salt to ease the stress
- a few extra sets of batteries for the airpump (1 pair of DD batteries for each pump)
The idea is to travel with the goldfish in the bigger plastic container. Cut holes into the lid of the container for oxygen exchange. The airpumps will supply the fish with air while traveling, and they come with a piece or tubing and an airstone. Its inside the batterie compartment. You'll need a pair of DD batteries to run the pump.
The container will only gonna be filled 1/4 with water at the most, the rest is sort of a splashing guard. You know, stepping on the brakes or driving around a corner, and the water moves. Don't wonna have that all over the car. The airpumps can be hung pretty easily on the rim or the handle of the container before you put the lid on, and fiddle the airline tubing/stone through the holes you cut into the lid earlier.
Now, for the travel itself, do not feed your fish for at least 4 days before the trip. That will cut down immensly on any ammonia buildup. Remember, there isn't gonna be a filter on those container for the duration of the trip.
A day before the trip, put the water in the container, so the temperature adjusts to the tank temperature. If you wonna take apart the tank/filter a day before as well, you can put the fish in the container a day ahead as well. Give a double dose of Prime. Just make sure you'll do a water change on the day of the trip then before you leave. Add 1 teaspoon per gl of water into the container.
Once its trip time, tape the lid to the container with duct tape. Then the container goes into the car (back seat, or back compartment in a minivan or SUV). Of course, try to avoid road bumps and such while you are at it - the sloshing sound will give it away if you should be more careful next time.
It'll be best if the container is in air condition, that reduces the stress, plus there is more oxygen in a cooler room than a warm one. Don't wonna pump warm air into the container via the airpump. Check on the fish every few hours when you get out for a drink or a stretch anyhow, test their water and add some Prime.
Once you arrive at your destination for that day (family or hotel), get the container inside, check for ammonia and do a nice big water change. That can either be done with some extra buckets that you brought along, or the python system that lets you do water changes from almost any faucet. Make sure the temperature is the same and the pH. If you use buckets, let the buckets sit for a while before you put the water in with the fish. That gives the water a chance to degas and stabalize the pH.
For those times that you are sleeping and are in hotels/family or friends, you can use the ordinary airpump for airsupply, so it isn't such a strain on the batteries.
Check ammonia in the morning again before you leave, if neccessary do another water change, always add double Prime, seal the lids, and off you go. You can repeat that process every night/day until you reach your destination.
If it is more than a week from when you first stopped feeding your fish until you reach your destination, you might wonna give them a very small meal at night, and then change their water nicely in the morning. Not feeding your fish for more than a week can put a strain on them, so a very slight meal once is a good idea.
How to travel with the filter? Well, whatever you do, do not let the media get dry, or without oxygen. I usually have a separate small container where I just put the media in, fill that container with dechlorinated water to just barely cover it all, and stick an airstone on a batterie operated airpump in it, plus a few crumbs of fish food. If you let the media get dry or without oxygen, the beneficial bacteria will die off, and you have to cycle the whole tank again once you get to WA. Too much stress on the fish. The fish food will give off the neccessary ammonia to "feed" the bacteria during your trip.
The latter version is one that I have practised at least, well, 2 times, and it worked pretty well. Not feeding, testing the ammonia levels frequently an doing water changes accordingly, is the most important aspect of it all.
Now, get those moving boxes going!
