I do have Mysis. I also have lrs, fish eggs, rods food, frozen zoo plankton and a few others. I keep a bunch on hand just to see what my fish like. I’ll be trying everything with her to see what she likes. But after I observed her better yesterday, she has a chunk missing out of her top fin near her head. I didn’t initially notice the injury by her fin was laid back. I hope she pulls through but I’m not going to get my hopes up. She swam around mostly yesterday, but didn’t go to the sand all day nor to sleep last night. Last time I checked her she was sleeping with the fairy wrasse.Nicee you have some mysis as well, like hakari(it’s smaller mysis’)? Brine is a good treat but not a ton of nutrition.
