I gave up on ever finding C. hastatus, and got myself a pod of C. pygmaeus instead.
However, they're not anywhere near fully grown - I'd say they're maybe 15mm TL.

So: at what size, approximately, can I expect them to mature?

Hi Mike
Male C. pygmaeus mature around that mark with them being fully grown at 25mm with females a little bit bigger and fully grown at 32mm, but i did have until recently a male at 27mm, he can be veiw on the catfish study group website in the photos for the 2005 open show third best in show.
