Please find attached the tientainensis (or what I think are!) photo's as promised. These are the only two that the owner (John Huddlestone) has left out of a group of about 6. The largest one (which we initially thought was a female, but may have been a male with hindsight) had a very pale body, much paler than the 'male' shown here. Some are naturally pale, with the darker ridge across the top of the body with patches along it, some are much solider in colour/pattern on the body and have a much more humped nape.
Sorry for the poor images but my camera is getting a bit dated now, and I couldnt get them in the right lighting.
Thanks to John for letting me photograph his fish.
