Hey there, unfortunately I never did get an identification on that species. I battled it for about a year, and then one day when I quit paying attention to the tank and they went away on their own (and replaced shortly after with a new species). Wish I could tell you exactly what I did, but I can't remember, I've torn everything down and sold everything, dinos pushed me out of the hobby after dealing with them for years straight.
Best of luck.
