hi i am so very new to tropicla fish having rescued a parrot fish three weeks ago as he was killing all the fish in the owners tank , put two smaller parrots with him and two large severum so as they can look after themselves as he is an agressive fish ,he will bite me too if i put my hand in the tank , when i first had him he was almost white but now is a nice shade of orange ,although he did try to bite and bump into the severum they fought back so now on the whole he puts up with them only bumping now and again . is there any thing you could help me with as i know nothing at all about fish ,i put them in a foor foot tank i will try to put a photo in for you regards norma
