Captive Bred Venusta Angelfish

[i cant think]

I have a couple of questions on the Venusta Angel, it’s by far one of my top 3 favourite dwarf angels, and I have the opportunity to source a captive bred Venusta.
If you’ve never heard of this fish, this is an adult :)

So, here’s the questions I’ve got!
1. If I got a Capive Bred with the lack of purple, and I mean it’s already an inch long with 75% yellow and maybe 25% purple, would the ratio eventually change to more purple than yellow?

2. How long does it take to go from an inch if not 0.5 inch, to even close to the adult size (4 inches)? I’d assume at least 5 years if not longer, but I’ve watched Emperor juveniles grow within a few months to a decent size.

3. Are there any corals I’d have to watch out for specifically - I already don’t keep many Micromussa (other than a Holy Grail Micro), and want to focus primarily on torches, hammers and gonis with the odd random LPS like chalices.

4. What is there swim pattern like? I’ve kept other large and dwarf angels, they’re always chilled out swimmers compared to Tangs and other large fish we commonly keep, so I’d assume these are fairly similar in swimming style to deeper water anthias where they stay closer to the rocks and aren’t too active, just gracefully hunting.

I’d probably keep this in my 3 foot nano (25G tank) for a long time if I can before it would have to go into my 5 footer - by which point if the growth rate is that painfully slow, I’d have room - if not a larger tank!
Plus, a photo of my multicolour angel - I love the “obscure” rarer angels if you can’t tell!

1. I do not think so. The largest change will be the lack of a faint white bar near the base of the caudal fin that is present in juveniles. The amount of yellow or blue is an individual difference. Bali Aquarich's Venustus (which if you're in America, this is usually where your captive bred ones are from) tend to have a considerable amount of yellow compared to most others.
2. Definitely less than 5 years. Most Centropyge's average adult life span is under a few years. This depends on how often you feed.
3. I don't know.
4. Paracentropyge aren't really "hunters" and venustus swim very similarly in captivity as other dwarf angels. In the wild they'll often swim upside down, but most reef tanks are not designed for them to do that. I'm not sure what you mean by deeper water Anthias, but Venustus will actively forage. They are not primarily a planktivore like an Anthias - they have not much in common with deepwater Anthias besides being slightly deepwater. They graze just like most Centropyge/Paracentropyge. They love algae.
5. Just a warning that I would not trust a multicolor with a venustus, they seem to be one of the meaner dwarfs. Good idea on the grow out tank. I recommend this.
