[quote="mikev"]Hmmm.... is the 1st Martin's Gastro a species or a variation?[quote]
I thought originally, based on an original description that this was
Gastromyzon ridens. Both these fish were thought (possibly) to be part of a
G. ridens "complex" by Dr. Tan.
By the way....these colour differences are pretty accurate, and this is 3 different fish depicted.
Martin.
