Very, very nice comments
They are my photos and my tank
I'm not a proffesional photographer - but I like fish and photography. My camera is Konica Minolta A200 - it's not SLR, but old, powerfull compact only.
Oscars - they are subadult fisches, about 8-9 months old. In my aquarium - 7 months. The biggest have about 25-27 cm long.
Some words about tank: 1000 liters, 260x65x60 centimeters. Filtration: sump with sponges and ceramics. Pump: AquaMedic OR2500, heater Tetra 300W. Temperature in tank: minimum 21 degrees of Celsius (now about 25 - summer

), pH about 8, GH about 28, KH about 18, NH3-0, NO2-0, NO3 - 10 to 30.
