Both are very nice fishes. I like the Auromarginatus; these fishes have an awesome body shape, I love how they swim.

My brother has a Niger Trigger; and it looks amazing. Yeah, my bro keep glass covers on his tank because of the jumping.
As for the Rubrimarginatus, thats a nice fish too, adds some nice colourful, movement to the tank.
I managed to get hold of another slightly different type of Strawberry shortcake.

This one is a faster grower. I already made a frag of it and it has nicely encrusted. My tank had about 15ppm nitrates, but it still is holding very good colour. I am doing more water changes to bring the nitrates.
The person I got it from is a retailer, he cultured the shortcake for a year. He is not releasing it yet, but when I visited his place, he sold me a frag of it.

This one has the same signature green base with pink tips. Lovely.
But it just shows that cultured corals are hardier and better at holding colour.
