Mating behavior? (A.cruzi)

[Lilia Stepanova <ls691035@bcm.tmc.edu>]

Hi to all!

What is the normal mating behavior in Apistos? (I have A.cruzi, but 
think, here is a common pattern). Some time ago male started to court 
female, and both become of very nice bright colors - male with brihgt 
blue specles, female bright yellow with black spots. They both seemed 
happy and I really expected the spawn soon. But after a while male 
changed his behavior - he chases female around and calms down only then 
he manages to get her into the cave. That would be nice, but not the the 
extreme - in general resembles an ortodox moslem married to a modern 
feminist. He does not want to let her out and she does not want to stay 
in. He chases her around untill she is in the cave (any one of three), 
does not let her even eat normally, she now has shredded caudal and turns 
gray in his presence, although in his absence she is the same bright 
yellow). 

Is it normal behavior or she really does ot like him? Do I need to do 
something to help them? Do they need any treatment for shredded fins?

Thanks
