Loaches Online Forum

Why is the coloration on the two pair of ventral fins on some clown loaches orange and on others the second pair of ventral fins are black with a tinge or orange or black and almost clear instead of orange ?

Here's some info on color in Clown Loaches. I am not sure if it will answer your question, but it may get you started until someone woth more info comes along.

it depends on where the clown was caught as they are not just from one place and there are colouration differences.
going of the colour mine was caught from Borneo.
