Showa's are starting to become interesting

The showa are getting interesting, and there's a whole new dictionary of traits for me to decipher! Here are a few examples of a few that look vaguely like showa! On the Tancho... the black around the scales; which bits are coming or is it all going...

Pictures below show the showa at around 1.5 inches long.

Currently, all showa's are in their own growing on tank - and we're growing on most of the spawning as a learning experience; and I've used the other two bays on Sharkey 2018.
