Looking at the photo of your setup, you've just rushed out, bought the first tank you saw, bunged in some plastic plants, and then immediately overstocked your tank with fish. Havn't you? Go on, admit it!
I bet you didn't even cycle the tank first!!!!
My God in heaven, may you have the man-flesh flayed from your puny frame. Damn your eyes!

PS I'd recommend getting another fish in there - they prefer shoals of 6 and above. You have only 5. 8)
