[Bapeluso]

there isn't a ceiling fan, but a couple vents in the middle of the room in the ceiling on either side of the tank.

Its ok, the helps appreciated. Theres few pests in the system. There's a few Flatworms that have been in the system, but have a melanurus thats keeping them in check. Never seen any on the euphyllia though. Also have a few aiptasia, but the filefish keeps the majority in check or i get them with aiptasia x. Have dipped 99 percent of the corals before introduction into the system. Like I've said, the corals will be fully extended with no signs of bother, then will up and leave

Have you seen fish picking at coral? What's your fish stock? Filefish apparently sometimes do pick, mine has never.

I've had fish pick before, but do not believe they are picking. Normally when they pick, at least part of the coral retracts. Havnt seen it. Also, the filefish is about the size of a dime. Hes super tiny
