  1. Default water changes - may be a silly question?

    Water changes with the stone vacuum always strikes me as quite invasive to the tank. Does it stress the fish much as somehow I can't see how it doesn't, yet I also completely appreciate the need to keep water quality sorted. Is it better to do small but regular water changes or bigger but less frequent re stress. Comments, hints and tips appreciated.

    I only clean about 1/2 to 1/3 of the gravel with each water change. That way, the fish always have a place or a area in the tank to go and hide should they become stressed, but I have not noticed my fish getting stressed out by a water change.
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    Some fish it will stress a bit and they go hide and they are fine. Other fish are curious and get in the way and still others are indifferent. It certainly is no reason to put off or limit the amount of water changes. The fish that get stress usually get used to it over time, and if not just make sure they have somewhere to feel safe during the water change.
    When I go fishing I just throw sharp rocks in the water and wait for the dead fish to float to the top... Kingfisher
    Everything happens for a reason. Sometimes that reason is you are stupid and make bad decisions.

    I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.

    Dear naps, sorry I hated you so much when I was a child... Love me

    I'll have to capture it some time but I find my platies come right up to my hand/arm and start picking at it like their hungry while I do gravel vacs. I have a GBR that doesn't seem at all scared of me. Could probably feed either GBR or platies right from my hand. On the other hand my blackskirt tetras and bulldog pleco run to the other side.

    i think any water-change is stressful for the fish, but not very much. and as some others have said each fish is different.
    the stress of bad water quality if SO much more than the one caused by a water-change.
    i don't think a water change is ever a bad idea as long as the ph and temp are close.
    i hear some people say, "i kept a goldfish in a bowl and it lived for a year."
    they don't know how lucky they were and all goldfish live at least 15 years in proper conditions.
    that is equal to saying my human lived in his closet for 5 years!

    agree with above. The less you mess with your tank the better - but water quality is a higher priority than not freaking your fish out. Each species reacts differently, but I've never seen a fish up and die of shock after a water change, but poor water quality does kill fish.
