Wow... is there room for any water in there?
But honestly, you're going to have to do something about your stocking levels. That's just way too many fish in a 12g to not have water quality issues. You may be fine now, but only doing water changes every 2 weeks... and too big of ones too, in my opinion (40% PWC
)... is going to eventually catch up to you. What's the tanks pH and alkalinity just before you do a water change?
