I have two blue paradise gouramis and one dwarf gouramis that are "supposed" to be peacful fish (so says walmart) but one of the BPG (the one i like most because of its bright orange and blue stripes) (the other one is more blue and isnt as pretty) is being picked on hard core by the other one and by the dwarf gouramis. They also fight eachother quite a bit... At first I thought they may have just been playing around or whatever... but it got pretty bad. I had to remove the two of them and place them in a seperate tank where they continue to battle on. the other one (the one i like) does just fine with all other fish. is it normal for these fish to be so aggressive? its like having two male bettas together with a female one all at once. their gills would flare up (it appeared to be) and they would go crazy.
