Just curious as to why the tankmates list seems to be very inaccurate to me. I have my horses with some lps and sps corals. On the list it states hammer, frogspawn and bubble corals as defcon 4 and duncans as only 2 I believe. I was thinking about that and before my horses came I was going to get rid of those corals. I then started to really think about why. These corals are listed as aggressive but that is only to other corals not fish or inverts. Then I was thinking of the duncans, well, they are a lot like an anemone and very sticky. They are much more dangerous than lps corals. My horses actually like to hitch onto the stalks of the hammer and frogspawn. Now I'm not sure what these corals would do to very small babies or dwarves but they seem to be very safe with my horses.
