Acros that have been in the hobby for a long time generally are not able to be IDed to the species level because of deformation.
A. convexa is millepora-like, and given PC rainbows have thick, rounded radials, they're probably not convexa.
What do you mean by deformation though, do corals overtime in captivity get deformed in the physical sense? or in the sense of different tank conditions will produce different growth patternsAcros that have been in the hobby for a long time generally are not able to be IDed to the species level because of deformation.

As for Paletta Pink Tip, that one's also not A. tenuis given Paletta's (also) rounded radials in contrast to tenuis's labellate, flared radials.

As for Fox Flame, A. appressa is a a valid guess, but there are also other species to rule out, like valida, nana, willisae, etc.

On the note about DNA analysis, DNA analysis is not the end-all-be-all, as molecular methods alone cannot identify a coral species. Corals thought to be of the same species but either from different localities or of slightly differing morphology will often produce differing DNA results with genetic analysis. This is because many of what are thought to be distinct species are actually cryptic species complexes which need detangling. Modern coral taxonomists have to use not just use DNA analysis, but also compare with type specimens and original descriptions, and collect from type localities whenever possible to produce topotypes which most closely match the studied species for molecular sampling whenever possible.
Corals tend to become deformed overtime in aquariums for reasons beyond our knowledge or control. By deformation I mean morphologically "softening": corals tend to lose corallite definition as flesh/polyps inflate/extend more. In Acropora this is expressed by more rounded thecae and irregular branching/growth form.What do you mean by deformation though, do corals overtime in captivity get deformed in the physical sense? or in the sense of different tank conditions will produce different growth patternsAcros that have been in the hobby for a long time generally are not able to be IDed to the species level because of deformation.

You especially see this in systems with low intensity lighting, overly blue lighting, low flow. Any environment drastically different from their natural environment.
Appreciate the in-depth explanation, just further serving to illustrate why species identification is tough, especially for hobbyist corals. I'm not surprised I was likely wrong on my assertions.Acros that have been in the hobby for a long time generally are not able to be IDed to the species level because of deformation.
