PB Cups stretching high up

[AFHokie]

So my PB Cup zoas are always stretched even high up in the tank. I started them low but they were always stretched out. I currently have them as the highest zoas in my tank and almost highest of all frags yet they still stretch.

Are these naturally long-stalked zoas?

Could it be flow and not light causing them to stretch? I ask because my pandoras were also always long at one point but I changed their position along the sand, light relatively the same but flow different and they stopped stretching.

PBs are right behind black clown in wider shot.

They may start to gradually contract at some point - or it could be they're just trying to get the ideal light. In any event, I wouldn't worry about it - they look healthy otherwise.

Thanks. They do seem to be doing well, like you said. Popping of off a couple new polyps too.
