i have a pair of red oscar but the problem is they are very dull
THEY DO NOT RECOGNISE ME
THEY SPEND MOST OF THERE TIME LYING ON THE AQUARIUM SIDE OR AT TOP
THEY DO NOT SWIM MUCH BUT EAT FOOD
hmm is your water okay check for nitrates or nitrites
what kind of decorations do you have and filtration adding some extra current could help
do they have any tank mates adding some other fish could help them to be more active and more competition for food will help them wan't to get your attention
