Added my first fish, a group of 12 Corydoras Sterbia to my 240L tank 3 days ago. They seem to not want to settle. They spend almost every waking minute going back and forth along the glass at the mid to high level of the tank, particularly at the back.
I've read on other sites that glass surfing is a normal behaviour, while others have said its from stress. From my perspective it looks stressful pacing back and forth all day!
I've been testing the water twice a day, once before the CO2 comes on & during the lighting. Parameters seem perfect, so I'm hoping it's just time they need from the move. Would think if there was an issue the amano shrimp would suffer, but they are thriving.
I've read Corys like very oxygenated water, so I'm concerned the CO2 might bother them & have turned it down a bit. I've got an oxygenator that I haven't used yet, but will try running that at night when lights are off to see if that helps.
I was wondering if anyone else has experienced this behaviour when adding Cory's to their tank?
