The percentage of people that try under 6 months is much higher FAILURE than those that have had their tanks up and running and already been through the hic-ups of new tank life.
Then again there are some people that never have a single hic-up from cycle to end of tank.
Good husbandry, maintaining tank parameters, and patience wins hands down.
Personally I would much rather wait a bit longer and have success than kill a $xxx anemone and livestock because I 'forgot' to turn of a doser I installed yesterday.
