DeMartini, I have a question about your cube.... I noticed you have the frogspawn all the way at the top (like I have mine) and I was curious to ask, when you do a water change how do you deal with it? Do you move it down? When i do my water changes I move him down because sudden loss of water his tips get all crushed up by its body/rocks... How do you deal with him and water changes, it seems like u have no space to put him lower during a water change so maybe you have a good idea/trick ?
