When doing a partial water change/gravel vaccum, is it a must for you to disturb the entire gravel surface? Or can u just pick a spot, burrow down to the plates, and suck out whatever comes thru the plates? Thanks!
I have several neons, and I don't want them getting lost/stuck under gravel I sweep around when vaccuming. This has happened in the past, because they fit into their surroundings so well, also I want to do what is least stressful on my fish.
