Ok, been a while but an update, they had spawned once, while in the community tank, nothing came of it, so I moved them into their mostly own tank, with just three guppies and a pleco for company. Just last night they have spawned again, my question is should I chance doing a water change? I don't want to spook them and cause them to eat the eggs. It's a 20 gallon tank. If I avoid doing gravel vacs should I be able to sneak out some water without freaking them out? Or should I just wait it out the 7 days and then move mommy and daddy back to the community tank at that point?
