On r2r one of them feeds white worms. Here in us you can buy starter cultures and grow them over time. Can also feed black worms to the fish. They are just harder to culture then need submerged and a little more work.Its strange, they're not bothered about live food other than what a few of them pick off the rocks and sand bed. I suppose I should be pleased as I don't have a refugium or anywhere to breed my own. Currently my tank inhabitants only get frozen food, algae pellets and soon nori sheets. I add live copepods to the tank regularly so they might be getting eaten by my smaller fish and inverts.
Haha, snail rescue is always fun, however, mine have just been flipping them over. What you had to sounds like a pain, hopefully you can get that rectified so it doesn't happen again.
Great news about the Royal Gramma.
I've not heard of or seen white worms as food for the fish, nowhere have i seen them being sold at UK fish stores. I don't feed flake and have never done so but making your own food sounds interesting.
I'm planning to take whole oysters, and try to find some fish guts, frozen shrimp, and maybe some whole sardines or fish of some sort. Mixing it with some selcom and other vitamins blend and freeze. BRS has a video on reef chilli so I'll watch that again and make my own little mix
