I do know that the frogspawn, and the branching hammer are rather aggresive, and are not a good idea for our horses. I will try, and find the msg listing the various corals acceptable for our buddies, but my computer crashed a few weeks ago, and I’ve lost most of my notes. I’m sure one of our more experienced members will update you shortly, but PLEASE, do not spend any money on corals that you are not 100% sure about. It is not a good idea to take the lfs’s opionions either.
Best Regards/Good luck
