I have what I believe to be a pair of A.macmasteri or Viejitas. The male and female have been together since the beginning. However, each time the female comes around he flares and darts at her. He continues this for a little bit until she completely swims away. I have a 29 gallon that is heavily planted with 2 large pieces of driftwood and a rock cave. Any tips or helpful insights as to this behavior?
