I have got a pair of baby Albino Oscar's (about a week back), added them to my 100 gal tank. Now one of the Oscars is acting very Wierd, it is not taking food, reflexes are very slow, settles down on the bottom of the tank or just floats on top and takes deep breathes (gills expands slowly in and out). Please let me know what is worong with him? I am very concerned - Rahul
