Can you get the frenzy from LFS? Or if it’s online do they ship to australiaIn regards to food, I am personally a fan of LRS reef frenzy. It has a ton of ingredients and good nutritional value. I thaw mine to tank temp in a little bit of tank water, and turn my pumps off for 10 minutes as I feed.
Being sure the food is thawed and letting it disperse as small pieces around the tank might help you out overall. My fish and inverts love the stuff.
That being said, you probably will have the most success with some pods.
