they don't get tattooed what fucking morons they've been coloring fish for a long time now, it's a dye thats injected into the fish.

How is the dye applied?
Intrigued as to how the dye was applied we decided to carry out a little research.
A few coloured glassfish were sedated in MS222 anaesthetic and observed under a binocular microscope. It became apparent that the dye is not on the surface of the fish, but lay under the epidermis.
Furthermore, the dye appeared fluid and could be moved slightly by gently squeezing the coloured area.
This suggested that it must have been injected into the fish at various sites over the body in order to form the distinctive colour patterns.
Our fears were confirmed a few years later when we were shown photographs of the colouring process, revealing that each fish is individually injected using a syringe and needle.
The practice of dye injection is undertaken by fish farmers in some regions of Asia (but not Singapore as far as we know).
Clearly, the common name "painted glassfish" is a cruelly misleading description.
If one considers the relative bore size of the injection needle with that of a glassfish, it would be the equivalent of us receiving several jabs using a needle of pencil-sized diameter - not a pleasant thought.
As experienced fish scientists, we would never dream of injecting fish of such small size. No wonder the injection process is alleged to cause high mortalities.
