I recently purchased 2 discus (? blue diamond), they fought (pecking order etc) so I purchased another 2 ( ?pigeon blood) to "spread the load". I however am still left with one fish (the smallest) that is constantly picked on, and so is now in hiding. The biggest fish is about 5cm diameter, the smallest prob 3.5cm. I am feeding the smaller fish by pressing food tablets against the glass which he seems to be eating, so I am not overly concerned with him starving to death. However I would prefer not to feed him this way, and would prefer him integrated into the tank community. Does anyone have any ideas as to how
(A) I can give him more confidence
(B) I can stop the other one picking on him.
Please note it seems to only be the pigeon blood who picks on him. The blue diamonds tend to leave him alone.
Thanks in advance
