4" in diameter, WYSIWYG and fully conditioned to life in a reef aquarium! These screaming blue and pink tips and nuclear tentacles will blow your mind! This is a perfect torch for someone just getting started with Euphyllia Torch Corals do well in medium lighting, that said, don't place them in par over 175 or so as they can get burned. They also prefer an alternating low to medium-low flow. In regards to feeding, I would recommend target feeding it once a week with a high quality meaty frozen food to keep it fat, flowing and happy, lol. Keep in mind that Torch Corals will sting almost all other corals, so make sure to give them plenty of room. Frogspawn are the one exception. Hammers however, will be nuked and killed if placed too close.
