Yesterday I added 3 male guppies to my boyfriend's cycled 20 gal tall tank that I set up for him. Aside from a few live plants that are all healthy and growing, they are the first living thing to enter it. They were just fine yesterday and were showing no signs of stress whatsoever. All 3 of them stuck together.
Today the largest male (orange) is constantly chasing another one (blue). It's strange because he is only going after the blue - my yellow guppie is completely being left alone. The blue, who used to be very active, just hides near the bottom now... unless he's being chased, which is 90% of the time.
Will this harassment be harmful for my blue? I understand that males often fight for dominance but this is entirely one sided. They've never "faced off" or anything.
I've never owned guppies before so I'm not sure how their behavior works. Will the aggressive orange harass other community fish (my boyfriend wants cories and maybe tetras)? If so, should I remove him?
