SPS colonies growing into another?

[swordfight]

Typically the same species can coexist, but different species they'll end up eating eachother.
I found out the hard way when my frags flipped or toppled over hitting another.
Funny thing I noticed is the same species didn't have a scratch, while others had a warfare overnight.

Often times yes, but not always. As I said in an earlier post, I once had a Hydnopora frag growing in the middle of an A. millepora colony and the two were fine. It is very rare for an acropora to not take any aggression from a Hydnophora so I am not really sure what was happening here but it was awesome.

Hydnophora's are known to be aggressive, and milli's are no different.
Those 2 living together is like keeping a shark with lazers attached in a lions den.

Millis are agressive? How so?

Sorry, still trying to get a grasp on mixing sps.

I have a couple of colonies that have grown together and survived. The easiest was my Tyree Ponepei Birdsnest and and ORA Bird of Paradise, they are so intertwined it would be impossible to separate. I also have Red Monti Cap, Tyree Undata, and ATL Appleberry monties all grown together in one mass, and last I have an unknown acro, look like it could be an Abrotanoides, that has grown into my Tyree AE Rainbow Stylo and Pink Pocci. I did not try to do this they just grew together and did not want to rip them out and reposition, so took the chance and just let them do whatever came naturally to them and there was some fighting at contact points but nothing that really damaged any of the colonies, now they all live in harmony :bigsmile:

I usually rate the SPS corals from aggressiveness by the protruding polyps, longer polyps typically mean more aggression.
Just give the corals the space they need and you won't have to worry about a thing.

+1 on Millies. They are very aggressive as well as Prostratas. I would not put them next to another SPS unless it was another Millie. I have had two millies touch without damage, but any other sps that a millie touched has gotten severely stung. As for Hydnos, I have found one coral worse than them. The hollywood stunner chalice. I had one completely decimate my hydno colony. Other than that coral I havent seen anything kill a hydno. They are just plain mean corals :xd:

My ORA Red Planet has taken out an LPS (acan or something similar to it), and is currently growing over some plain montipora cap and an ORA Miami Orchid. I'd say that is pretty aggressive!

Hydno's have always been aggressive, was never big on those corals.

Prostrata's on the other hand, are very nice!
