I taught my tiger SH to eat dried market shrimps. and after a week I was surprised to see a those blue and green scales at the top of thier lateral lines
well its not really that visible just a tinge,but i can compare ,,its blue scales gradienting to green...theres a bit of discrepancy on its color compared to before..Ill post some pics as soon,my digicam's batt is low,gonna recharge it later
