Hi all I have just come home to find one of my Sterbai Corydoras dead a neon tetra dead and 2 female guppies dead. Now the tank has been setup for years and the stats are all good only thing I have noticed is since I moved my Hydor Ario 4 bubble diffuser the other day it has decided to make tiny fine bubbles instead of big ones that hit the surface quickly. Now since it has done this I have noticed it only has to be on for 2mins before the whole tank is filled with tiny micro bubbles so my question is can too much dissolved oxygen be killing my fish? As my corydoras never die they are always the most hardy fish I have had.
P.S.My Ario 4 kicks in once the lights go out as i did read somewhere that the plants take in the oxygen when its dark and take in co2 when its light. And there isnt any bully fish in the tank causing this.
Thanks
