I have a pair of betta smaragdina and two pairs of imbellis. I keep each species in their own 20 gallon long NPT.
1.do wilds have a few green iridesent scales on the dorsal half of their body?
There are over 50 species of bettas so yes some of them do, some don't. Some have iridescence in different colors. Metallic colors in betta splendens were originally sourced from wild splendens complex fish. Generally most species are dull with one or two very vibrant areas, typically in the fins or gills.
2. Do the tails and anal fins always have mostly red?
No, red is common in splendens complex species and in several other complexes, but individuals within these species can have no red at all. I have seen imbellis and mahachai that were only black and blue. My smaragdina male has very little red and my female is solid brown.
3. Do the tails have green rays on them?
No, not always. They could be only red or blue or back or a mix.
4. Do you think the common domestic blue betta you see in pet stores looks very different from a wild caught/wild type? How?
Yes, very. It's obvious to me that wild betta species have features designed for function and survival over looks. Domestic bettas have large, flowy fins that impede movement and camouflage, plus color combinations and body shapes that have been introduced through artificial selection. Also many wild species are differently sized, some regularly getting over 3 inches long. Others are smaller, and others are mouthbrooders with jutting underbites that look very different from bubblenester mouths.
