Thanks. Yeah, I've left my lights unplugged for today. They were pretty much in sleep mode within 5 minutes of turning off the lights last night.
The dottyback is an orchid dottyback, Psuedochromis fridmani. Unfortunately I can't get good pictures of him as he's far too fast, and those that I do get, the colour is way way off. He shows up as all-the-way purple in pictures, but in person is more of a pink with a subtle suggestion of purple.
The doliatus looks *exactly* like a 1.5" version of the virgatus, so much so that I'm not 100% certain it isn't a virgatus, but has blue stripes all the way back to tail instead of spots. Hopefully in time it will be more evident. I'll see what I can do about pictures.
Here's a recent-ish (from August) picture of the virgatus:
