Although it is over 10 months old – it remains an interesting question.
I wonder why nobody else contributed to this thread.
I found it looking for informations about the intervals of water changes that paro breeders normally keep.
I have several tanks using no technical equipment, just some additional lighting in the winter months. No heating, no filter. My fishes are Badis species, Dario and Pseudosphromenus. Every week I change about 20% of the water in these tanks, and they run quite well.
Now, having my first paros, I found a number of forum posts or articles which say that paros do not like too frequent water changes. On the other hand – paros like very clean water with low conductivity.
How often do the experienced paro breeders here make water changes?
