I was thinking of making more water than I need for emergencies or because it would be convenient, but since so little is needed it’s not really necessary.
The peat filtered water in the aquarium changes and becomes softer over time, and as was written before new water raises the pH a little. But this increase is harmless, is this because fish are less sensitive to pH increases than decreases, and also because if it is within the range of acceptable conditions, they can stand a little fluctuation? If the water is soft enough and acidic enough are paroshpromenus not terribly delicate? Not that I would test their limits but I’m thinking about the fact that soft acidic water with organic material will not be totally stable. And it sounds like they will live and breed fine despite that. What are safe levels of change in their aquariums?
Noticed another thread about magazine articles- I have an issue of Aquarium Fish International from March 2011 that has an article about breeding parosphromenus.
