Please Help Help Help !!
I have done a water change a few weeks ago and today only just noticed 95% of the fish in my tank are swimming at the top head pointing towards the top... They are swimming in a motion as if either eating from the top of the water, or trying to get air....
My issue is I have done a full water check and everything is in order, the temp is also correct.
Is there a major issue here, am i going to wake up in the morning and the lot be gone ?
How can i make sure everything is okay ?
How can i add oxegen (if this is the problem?) to the tank ?
Thanks for your help.
