if it helps, i estimated the larger of the 2 eels i had to be 8". so that dismisses the possibility of it being one of the smaller ones which reportedly only get to 6".
i am really curious though about finding out what these suckers are because if they stay small enough ill consider trying to find one again for the next tank i set up. finding one will also be a problem cause they were shipped by mistake in place of peacock eels and to make things worse all the walmarts iv been to lately have quite selling peacocks in general.
