Hi, I went to Pier Aquatics today because I am moving all my tanks around after buying another cubed tank on Friday. Anyway, I bought a Centipede Knife Fish Steatogenys duidae, and 3 Archers. The Archers were listed as freshwater specifically. and I trust this shop more than any other shop I go to. However I have always heard there were no freshwater species and I was wondering if anyone had good info on whether there are? It doesn't really matter as I have a Brackish tank already and they will just be placed in there for the long run if needs be. I now have 3 tanks to stock really with my main 6x2x2 180gallon tank becoming an oddball tank for the Archers and Knifefish, plus others hopefully.
