Yes, that’s always been my principle, too.
But it’s like Peter says – paros never live in still waters with no flow. Even if it’s no raining season, there’s always a constant flow of seeping water trickling out of the forest grounds. They don’t live in totally stagnant water. And an aquarium with no water changes imitates stagnant water.
So I think it’s the best to change water regularly, but only in small amounts. To imitate the starting rain season (and thus the spawning period) we can change a greater part of the aquarium water. I use a sprinkling watering can to imitate rainfall.
I think this is the example nature gives us concerning paros.
