Victor...word of warning...on your grafted divercata....I suggest you cut it and grow out the purple part eventually the green will take over. I have had mine for one year already and its almost fully green. To prevent this I took a piece of the purple and grew it out. and then I eventually grafted the green back into the purple. It was pretty cool when i got it to work, since now I have two pieces.
As for the millie, your coloration is great. Mine has a ton of spots of green everywhere, but when lights are on the coral is super hairy you can barely see it. Only when i have atinics on do I see it. This i forsee as a future LE.
Monti cap is growing nicely thanks to you.
As for my grafted simplex. THis by far is one of the slowers ones i have growing in my tank
