. My pH is 8.2 and everything else is a flat 0 with a good air pump for oxygen levels and good filter carbon changes. i do weekly water changes and ended up doing multiple water changes this past week to try and save this last goby but it was unsuccessful. They all of a sudden start to become unactive and breathe heavily and within a week there gone. Im not blaming your store at all i just want to be clear. The pH might be a little low but thats the only thing i can think of but it doesnt seem deadly. Im just confused. i want to buy another one before the end of spring with a optimistic outlook unless you recommend me not to. Does anyone have any advice on what to do or are they just a fragile animal ? a:( 
also any chance you can get another color scheme insted of the grey with blue bars ??sorry for the long story
