The zoas look great! My Yodas and Time Machines look awesome in your tank
The Yodas and Wobbegongs are similar but the difference is the color shading and patterns. The skirts also have yellow and green bands on the Yodas. Wobbegongs tend to morph in and out of patterns depending on different tanks. Yodas will mainly morph out in color depending on different tanks. Also placement is a big part as well, Yodas like lower light and the Wobbegongs likes med-lowish light depending on your lighting of course but thats where the different tank part i mean.
The Yodas look better and better everyday heres a pic of them when colored up in my tank, pics MH 14k and blues.
But of course i have seen them look even better in a few other peoples tanks. I actually had them look better than that with more of the green and more patterns come in but i had to re-do my tank so they didnt like where i moved them now...
