I was feeding him mysis shrimp. I never ever really saw him eat. I just assumed he was eating. My mistake. He mostly just picked at our live rock. He ate all our aiptasia and feather dusters. The guy at a different lfs than we bought this fish from showed us a book tonight and it said that these type of fish are almost impossible to keep in the home aquarium. Gee...I wish I had known that sooner.
I'm pretty sure we starved him to death.
Anyway, I had my water tested tonight and my ph was 8.2, trites 0, trates 20ppm, and ammonia 0. My salinity was a little low because the lfs that sold us this fish accidentally sold us ro/di water instead of salt, and I put 10 gallons of that in when I did my last water change. Yikes!
My husband bought a yellow tang and a sand sifting goby tonight, so hopefully we'll have better luck with them. I'll post pictures once my lights go on in the morning.
jesatfis---royal grammas open their mouths REALLY wide and it looks like they're growling when their territory is being invaded!
