Here is a video of a pair of wild A. panduro that are in the process of getting ready to spawn. This species is one of the nijsseni-group apistos, and as such it can be pretty aggressive. They prefer to spawn in pairs, and other fish in the tank can take a pretty good beating from a dominant pair. This can be a problem when a pair is not fully bonded. If the male is not receptive to the advances of the female, or if an amorous male does not get the response he wants from a female, then there is a chance that the male can attack and kill the female. Mirror therapy can help… by using a mirror to solicit a territorial response by the pair, their bond is made stronger. You will see in the video that the male is very aggressive on the mirror… he hits it hard multiple times. The female will also join in on the defense, which is a good sign that the pair is bonding well.
