Goodish news, the Zippy Acro showed back up yesterday... Something pushed it out from behind the rock work enough that I saw the tip of the frag plug sticking out. It's either browned out from too little light or it bit the dust. I put it back on the rack so we'll see if it colors back up. Lights are just coming on and it looks like all 4 from BattleCorals are still happy (how can you tell if a polypless acro is happy? Color looks good but without any PE...
