Yeah, Ive never heard of an "Elephant Face" coral but there is a coral called "Elephant Skin". Its a SPS hard coral.
To be quite blunt - don't add anymore corals til' you can keep the ones you already have alive for a month or so. They really struggled aclimating and just because they opened doesn't mean they'll survive. Remember - SLOW is good.
Like Kevin said - 10 gal way to same for ornimental clams. I'd also steer clear from Brains in small tanks w/ other corals - their tenticles are long and they can be very aggressive towards other corals. Try something along the lines of Devils Hand or Wisker Corals (duncans) much easier and far less aggressive. Alot of corals just aren't good beginner corals, they need specific stuff and even specific feeding times.




LPS are Large polyp stonies, in other words they build calcium based skeletons. SPS are small polyp stonies again build skeletons. The difference between the two, is how much tissue covers the skeletons, usually you can see the exact shape of a SPS skeleton, an example being branching acroporas. LPS on the other hand form large soft tissues on top of the skeletons sometimes massive amounts sometimes just slightly larger then the skeletons, an expample of LPS would be that brain coral you posted a picture of.
The elephant face looks like a finger leather... or maybe even a devils hand... doesn't really matter though. I agree with Otherone, it's not a bad idea to see if you can keep these ones alive before adding more. I know now that you've started adding corals you don't want to stop... we've all been there... but be patient reef keeping requires alot of time and care, and you don't want to rush in, filling the tank with corals, only to have them all die... not only an expencive loss but sad as well. If the ones you've added are still alive and well (ideally showing signs of growth) in a few weeks to a month from now then go for it, add some more staggering additions of course, as they do add to the bioload a bit.


yep the should be ok
