hey i am not sure if anyone has ever had this problem but i think my plecos are fighting.....i have never had this happen before but recently i just introduced a Raphael catfish to my tank and the only other fish in the tank is a pair of 1.5in severums and the tank is a 60 gallon i dont understand what is going on. Are they fightingbecause there are two of them in there, are they fighting because of the the Raphael addition, or is it the Raphael the one causein all the problems....I need some help will seperating them into my other tanks and just getting a larger pleco and haveing that one in my 60 gallon fix the problem??
