I would agree with the majority of what you said. I have also kept A. granulatus in the same manner, rather successfully. I do beleive the higher temps is also important...85 is my target temp. I don't do water changes at near your stated rate. I generally target 30-50% H2O change on a weekly schedule.

It would be nice to see these bred in captivity on a regular basis thats for sure.

Cheers!
