My initial thought was that these were juvenile Entacmaea Quadricolor, a species this zoo has kept in their coral reef tank in the past, but there was no signage so I'm not entirely sure.
@Ebirah766 Thank you for the reply. They did used to be signposted, but this zoo have recently done a big pet peeve of mine when it comes to aquariums, removing the signage and replacing it with a little TV that's meant to play a slideshow of the species signs, but of course it wasn't working.
@Ebirah766 how do you identify this species when it does not have the inflated tentacle tips? I've been struggling to recognise this species because it's so variable!
@Jambi same here!! All the ones I've seen in the wild have very pronounced 'bubble tips', but in captivity it seems relatively few do. Honestly wouldn't surprise me if E. quadricolor is actually a complex of multiple species given it's variability - plus, in the wild it has distinct solitary and colonial forms that play host to different species of anemonefish (eg. Amphiprion biaculeatus only hosts the solitary form, and A. melanopus only the colonial form) - seems suspicious for cryptic species if you ask me!
