Yes definitely. If you go to your gallery page there will be a menu on the left hand side. One of the options is to add an album. You can add a saltwater album, a freshwater album, and whatever else you like. You can have nested albums if you want also. So someone could go to your gallery, go to your saltwater gallery, and then go to your yellowtail gallery if you wanted to be that specific about how you divide up the pictures. Don't be worried about making mistakes in there, you can always edit or delete anything that you don't want. Just try it out and let me know if you have specific questions.
