Hi Jim,
Yesterday (6 May) I noticed one of the LionFish swimming through the 3D coral. (The one in the centre above the clock.) Its tail went "through" the coral. My machine is a bit high end. It is a Gigabyte i7 motherboard with 12gb ram and a ATI 5780 graphics card. My resolution is 1920 X 1080 and I'm getting just over 111 fps. Sleep set at 10. With the exception of the starfish, all the fish are displaying. I have not noticed this effect before (11i) but then I don't see the fish swimming through the coral that often.
Great piece of software. Can't wait to see the new fish.
Regards
Ray
I have an Intel Mac running MAquarium 3.01. This morning I saw three different fish of varying sizes swim very close to the right side of the mouth of the small cave, where they promptly swam through the rock.
