I know its meant to be "easy" and have have asked Uncle Google many questions, but there are a few answers I can not find; 
 
1. First are daily water changes to lower the temp useful? 
2. What is a good "breeding" temperature? 
3. How many caves should I have? 
4. Does there colour appear more vivd when breeding? 
5. Is is a bad sign when the Male wont let the female in the cave at all, and he defiantly does NOT have any-thing in there (i.e eggs)
