This is why I am extra keen to get all of my fish when they’re small. It makes for an easier time pairing as they’re a lot more likely to still be female (or male in the case of Clownfish).

Yes, I wasn't trying to extrapolate that observation to any species other than orchid dottybacks.I disagree here, I believe fish should be kept in pairs where possible. Given a QT with a divider of some sort, the smallest individuals with an obvious size disparity, and some time, pairing dwarf angels should be straight forward.
Wittenrich's book has pages dedicated on how to keep dottyback pairs that are spawning regularly from killing each other. Orchids should not be considered the norm for dottybacks.
Agreed! You should always aim to keep your fish in pairs or social groups if possible (there are species wher it isn' possible and I usually avoid those). With some fish, especially those that don't change sex, it might be difficult but one should always try.I disagree here, I believe fish should be kept in pairs where possible.

Orchids form harems in the wild. For breeding them in captivity pairs are better as just one egg ball will hatch more larvae than you can handle.Matthew’s book sys that the vast majority of Dottybacks are protogynous hermaphrodites. His section on angels (which I assume he talks about both large and dwarfs) also says that for the most part they’re protogynous hermaphrodites and advocates putting either 2 small individuals together (monitoring for aggression and with hiding spots) or 1 large and 1 small. The no-no is two medium or large specimens. He says if they’re ignoring each other or at least not trying to kill each other outright, chances are at least one is still a female.
Since he’s the co-founder of Poma Labs I think he’s a fairly authoritative source. As for the Orchid, I don’t think he mentions having bred them via a harem rather than a pair, I’m not sure if that implies they breed only in pairs.
