This thread is right on time. I didn't read the whole thing and don't feel the need too.
BLUE SPOT PUFFER (Canthigaster solandri)
I have battled the vermetids for years. Super glue the hole shut, fill hole with kalkwasser, cut them off with pruners, jab a stainless rod filed to a point through them. For every big one I killed there was a handful of small ones waiting to grow big enough to get killed. Feed the tank, stir up the sand , blow off the rocks and they showed up everywhere. Bumble bee snails, copperband, longnose bff, hermits, emeralds, sally light foot, nothing ate them. Hell I gave rock an acid bath, soaked it in bleach and the vermetids were still alive, relentless.
I have a 150g SPS dominate tank that was left neglected and overgrown for quite a while. I broke down a bio cube and through in a Valentini and a Blue Spot puffer. Sure they nip at sps and eat zoas but who cared. There was enough SPS where they could graze for days and no zoanthids in the tank. They definitely pick at sps, eat the edges off monti, bite the corallites off acro. The good thing was they would pick at one coral then move on to another while the other healed up. Like they knew if they ate the whole thing they would cut off there food supply, but could they be that smart?
The last two weeks I have been cleaning the tank, donated most of the coral to a research facility and noticed.
HOLY CRAP, Vermitids are gone!!. well not completely but not plague proportions. there's a few here and there. I saw for the first time today, the blue spot puffer latch on to a vermetid snail and bit through the tube. I actually heard it outside the tank. Pretty cool sight. Still yet to see the Valentini eat one , but will be watching closely.
I have been debating the past couple days whether to take the puffers out, since I am redoing everything and don't have much acro for them to nibble on. I will be the guinea pig and keep them in and see what they eat for sure. I would not recommend putting them in your prized reef tank with you speckled kraks or beach bum , but if you don't care if things get nibbled on it could be worth a shot?
I have seen them eat Montipora, Acropora, and Zoanthids.
I have not seen them eat but can't say they won't eat. Euphyllia(torch, hammer, frog), Stylophora, Cyphastrea, Leptastrea, Leptoseris, Pavona, Chalice, Psammocora., Duncan or Candy Canes or Bubble tip nems, Aiptasia
I will post pics of nibbled on sps frags that are in the tank now and document. Hopefully they survive, if not I and I don;t see another vermetid an LPS tank is fine
