Letting the corals grow

With my sps pico, I want to just leave all the corals to just grow out. I am concerned about chemical warfare in a 4g tank and what will happen when there is no space?

In my experience sps don't normally use chemical terpenoids, but some will STN as sort of defence or self destruct mechanism if they come in contact with another coral. Seriatopora will definitely do it. I've got a purple digi that has done it when another more aggressive SPS grew into it.

May be true for many Acropora, but like any other group there are always 'black sheep'. I have a Red Planet that uses both a chemical blast and sweeper tentacles in it's quest for 'Reef Domination'.

Ok, I probably won't just leave the corals now lol

Yep the RP is pretty agressive and my JF Sour Twist beat the hell out of an encrusting monti when it got within 2-3mm of it's base. It didn't hit hard, but it knocked back the monti a cm or so.

 

Also, just because most of them don't release chemicals, they are ALL capable of stinging. I had an acro fall off my rack onto my acan garden and when I pulled the acro off the acan lord had lost 4 heads and the acro didn't have a scratch. In a small tank without large colonies - whoever strikes first is always the winner.

I have experienced some weird battles. I have intervened on a few. Here are some i have had:

GSP encroaching on zoas, gsp dies back some, then grows around the base and sides of a few zoas

Frogspawn 'killed' a sps frag that fell into it, flesh was gone skeleton, was white sps looked like nothing happened within a few weeks

acro and encrusting monti grew up against one another both had a 1-2mm band of dead flesh, both started growing a 'wall' along the line

encrusting monti encrusting over zoas

acro damaging pollicora with tentecales

 

By far acros seem to be the most deadly. I have watched sweepers from galaxea hit soft corals and the softies recover within a day or two. with acros it almost always involves some death.
