Hi Summer:

I've used a hypodermic needle to inject acrylic (not latex) paints  
(from an art supply store) just under the skin of a fairly wide  
variety of small fishes with variable success. It works great with  
some spp/sizes and poorly with others. You'll need to experiment, but  
I'd encourage you to try. In my experience, you're approaching the  
practical lower size limits at 70 mm, but it's worth trying nonetheless.

Most recently I was able to purchase a new (?) type of acrylic paint  
that was unusually low viscosity. The usual acrylic paint in my  
experience is like toothpaste and had to be diluted some form of  
sterile saline. The new stuff works very well.

This may be useful as well:

Lotrich VA, Meredith WH (1974) A technique and the effectiveness of  
various acrylic colors for subcutaneous marking of fish. Transactions  
of the American Fisheries Society 1: 140-142

Good luck!

Pete
