Would $16.99 USD be reasonable for a 12"-14" long Ropefish, and being it the thickness of a nickel is it too small...(seeing as my Senegal is 8"-9" long)
I have three of them and this is about the amount I paid for the largest, which is equal to the one you are looking at. The others I paid $12.99 for and were a little less than 12".
just to compare the price in Mountain Valley to the Philippines Ropefish in the philippines cost 11$. so probably that is a good enough price for your area.
