| All great points for the beginners. I would like to add a few that came to mind ( I am sure there will be more).
"Weigh heavily the origin of your livestock. Wild caught species will eventually hurt our hobby. Try to purchase tank raised livestock whenever possible"
and
"Take EVERYTHING slow."
and
"Document and log your progress. From your tank levels to your livestock. That information will become invaluable for seeing a problem in the early stages." |
