@Chlidonias neither coffinfish nor arrow crabs were present on my visit - was this on the same row of tanks that also had the green eel gobies and frogfish?
@DaLilFishie They were in the tanks pictured below. I think they were literally the first two tanks on entry - before the sardine tank - the Green Eel Gobies etc were after the sardine tank.
@Chlidonias ah, those tanks weren't there when I went, the first tank I saw was a fairly large reef tank. I believe Sunshine had a temporary deep sea display, perhaps those tanks were part of that and had been removed by my visit? What date did you visit?
