A variant of Bubble tip anemone (Entacmaea quadricolor)
Representative Bubble tip anemonephoto — a dedicated image of this exact morph isn't available yet.
The second officially recognized sunburst strain: red, orange or yellow tentacles (color shifts with lighting) over a bluish oral disc with white spotting, fading through bright green up the tentacles. The green carry-up is the main giveaway versus a Colorado.
📜 Backstory
Sold by Top Shelf Aquatics, Eye Catching Coral, Bulk Reef Supply, Coral Life and others. Along with the Colorado, the Chicago Sunburst (ChSB) is one of only two recognized 'official' sunburst strains. Eye Catching Coral states they acquired their original Chicago Sunburst stock from Tank It Easy in 2018. Natural wild-origin coloration propagated as captive splits; many yellow BTAs sold today are the yellow phase of a ChSB.
Keeper tips for this variant
Lighting changes its look dramatically — yellow under LEDs, redder under metal halide — so give it medium-to-high light (~150-350 PAR) and moderate flow, and let color settle before judging. Keep flow steady to encourage bubble development.
