i jst fed my oscars and severums prawns for the first time, but then i noticed that the water kept getting more and more cloudy soon it was very cloudy. is this normal? or do i have to do a water change or something. another funny thing was that the oscar thought that the albino catfish was a prawn and ate it only tail was sticking out 1/4 of body. i went to get the scoop net thing but when i came back the oscar had spit it out. am i overreacting to this cloudy water?
