Fish Fanatic
so Ive had my tank for 4 months or so, and the person i bought it from had it for a few months before me, apart from the 2 jewel cichlids i put in a separate tank all the fish have been living together happily for plenty of time, yet all of a sudden my parrot has decided he doesn't like my pleco. there's 2 in the tank and he's attacking the bigger one of the 2, why would he just decide all of a sudden he doesn't like him? any suggestions? and apart from removing one or the other does anyone have any suggestions on how to suppress the parrots aggression?
