I'm Worried about my clowns
I'm worried about my clowns, there the only to fish in my 100l tank and up till now they've been eating fine and swimming about as I would expect, I've had them 3months now.(the tank is 4months old now) My water is good and I do a 10l water change once a week.
The problem is this I went to work and all looked normal. Came home and my 2 clowns where both up on the top of the water near the filter inlet to I went to give then a poke to see if they are alive they both swam off, there now both swimming on the side of the glass and the back. Moving about a bit but aways in contact with a side.
The lights where off when I got home so I put them on to see the fish, could I have woke them up? Do they rest when the lights off?
Or could there a problem? Could they be sick?
