Aquarium Ornament Fish
How do i change the aquarium without upsetting the fish?

I want to change my aquarium, i want to change the gravel and the ornaments. But i dont want to disturb/upset my fish and kill them. I have had 2 of them for 4-5 years and they are pretty hardy but i am worried about shocking and killing the newer ones. How can i do this or what is the correct way to do it? I have a big tank and filter ect...
lol @ HAVI answer. thank u all for ur answers. I know wat2 do now

I don't understand what's up with people putting fish in buckets every time they clean their aquariums. In my opinion, if you have an established system, you can perform routine maintenance without having to take out any fish from your tank. Here are some recommendations to diminish stress on fish while changing water or decorations:

1. Use "Stress Coat" (from Aquarium Pharmaceuticals) to replace natural slime coating on fish.
2. I always start on one side of the tank so that fish can move to the other side while I'm siphoning gravel and changing decorations. After finishing the first half, then I continue cleaning the other half.
3. Remove decorations and move things around using aquarium tongs. Avoid submerging your whole arm inside the tank unless you have a big aquarium. Always use gloves.
4. Avoid extreme abrupt movements or tapping the glass since fish get stressed out with these interventions.
5. If you need to transfer your fish, always use soft mesh nets. Avoid chasing fish with one net in order to catch them. Use a very large net on one side and a smaller one on the other.
6. Long Handled Scrapers are ideal to clean algae on tank's internal surface without touching the water.
7. New water and old aquarium water should have similar temperatures to diminish shock. If possible, prepare new water (including conditioners and additives) in a separate container at least 24 hours before starting to clean your tank.

I hope these suggestions helps you during your cleaning routine.
