For those of you who know, I am planning on breeding fish for my Animal Companions class. I thought I was going to do convicts but found Dwarf Cockatoos at a pet shop about a half an hour away and decided they'd be a better choice. I have not set the tank up yet so don't know my exact water parameters but do know our water goes through a filter that removes some of the minerals so the water shouldn't be too hard but still have minerals in it. The one thing I do know is that our water has a lot of calcium. Will this affect the breeding of the cichlids? I know keeping them is fairly easy but hatching the eggs is a little more difficult. I will get exact water parameters as soon as I get a test kit.
