    Hello all,
    I have a mainly lps tank with the following corals
    Torch
    Frogspawn
    Hammer
    acan
    favia
    candycanes
    pink goni
    aleviapora
    war coral
    zoas
    mushrooms
    and a few assorted other LPS

    My question is I spot feed reef roids 1-2 times a week with all pumps and return pump off. I never see feeding tentacles out on my candy canes, acans, my goni retracts when spot fed ( dont know if thats normal), my zoas close up, and my torch frogspawn and hammer is indifferent about it.
    I see these amazing pictures esp of acans showing feeding tentacles but no matter what I do I never see such things in my tank. Anyone know why?

    water params
    salt: 1.027
    Calc: 425
    Alk: 9.1
    Mag: 1350
    Phos: .21
    Nitrate: 4

    I usually feed late in the day when that tank is transitioning into lunar lighting

    Out of all those corals only the candy cane , acan , Favia , war coral
    Will give a feeding response and it’s mostly at night. Try looking at them 2 hours after lights out

    Try KZ LPS Amino 30mins prior to feeding Roids and see if that changes. I had great success with that. It also depends on the nutrients in your water Column.

    Goniopora do close up, but very slowly spray above them... that is a good thing when they look like they close up ( the stacks retract but the polyps stay open) typical response to feeding.

    Try spraying them with the liquid from your thawed frozen food. About 5 minutes later, my large, hungry LPS (trachys, Acanthophyllia, bowerbankis, lobos) open up and are ready to feed. Then I drop some pellets or meaty bits of LRS on them and they inhale them. Regular feedings (2-3 times a week) will condition them to stay open.
