I got my 3 new sps. A pocillipora, a green stylo, and a montipora cap. I sat the poc, and they stylo on their sides, and they are doing great, but on aquarium advice a guy said that if they are leaning against something, they will get RTN (Rapid Tissue Neucrosis) and they will die. I asked on #reefs on the irc and to brian on #oceanreef and they said that its perfectly fine, and all it will do is grow onto the rock. I just want to check with you guys to see your perseption.
