I picked one of these up yesterday... I knew what I was getting into and I know it's chances of living are pretty slim. So I thought I'd share my experience at the very least to put others off buying one! Should I manage to keep it alive, then this will hopefully become a useful bit of info. I will try to keep this thread as up to date as possible, with regular picture updates. First up, I believe it is a Himerometra robustipinna - red feather star - hereforward referred to as FS... unless someone wishes to name it Acclimation: Drip acclimated over 4 hours. Quarantine: Not quarantined as I felt it needed to be in the DT asap. DT params: Temp 81f Salinity 1.025 Ammonia & nitrite 0 No3 5ppm Ca 440 Mag 1380 Alk 8.8dkh pH 8 Tank specs: 320g, 8'3" long. Skimmer Caulerpa refuge Biopellets, GFO and carbon via fluidised reactors Flow provided by a jebao cp55 on intermittent wave mode and max wavelength and power, 3 x 6000lph wavemakers and 1 20000lph wavemaker all on permanently. On introduction to the tank I released the FS midwater and allowed it to settle wherever it wanted. It selected a spot with good flow, midwater under a slight overhang. After giving it a couple of hours to settle, I attempted to feed it... I was worried it wouldn't have been fed sufficiently in the LFS and understood that the vast majority of these die from starvation. I fed my own homebrew frozen food (basically a load of seafood with all the horrible bits left in, blended up with Caulerpa and omega 3 oil). To my surprise I could see the FS catching particles and passing them down channels at the centre of each arm towards the mouth. The items captured were just big enough to make out by eye, but to small to capture properly on camera. I would guess around 0.1/0.2mm. I fed twice on day one and had the same feeding response each time.
