I have a pair of Peacock Gudgeons who appear to be spawning for the first time in my 40B! She has the yellow spot on her belly and he has picked out a cave so I am excited about that! My question is that I still need to do a water change this week. Is it best to put it off a few days as not to interrupt them? Or should I just go ahead and do the water change to ensure that they have ideal water conditions? Thanks for the help!
