| || | Antisocial Tetra??
A week ago we introduced three long-finned black skirt tetras into our tank which is in the process of cycling. All the fish in the tank are happy, healthy, and very active except for one of the tetras which seems to actually hide from the other two.
My initial reaction was that it seemed he was stressed from all the jostling around so I figured he would just perk up over the week. He hasn't so I though maybe he's just a fifth wheel and needs a few more friends so I picked up another three. Now, the five are schooling and he is actually hiding in the pleco cave (the pleco seems pretty chill about the whole thing).
A few days ago I noticed that he had signs of being nipped at. Is he perhaps being bullied? I suspect that the two other original tetras are a male/female that have paired up (one is quite large and growing and the other is smaller with a wider anal fin with serious fin nip). Is it possible that the male from the pair is chasing the third away? What can we do to make the isolated one more comfortable?
