Like what the title says can you do water changes too much? Because I did water changes last night and I looked in my 55 gal and my Female isn't acting the greatest! And she was fine before. Guarding over the nest everything! I just dont get this! Should I slow down on water changes? I do weekly water changes usually around 30-50%. Im I doing something wrong? Last weekend I syphoned my tanks except for the 20 gal L because I just set that one up!
