Yes those are the ones. Hang them inside without the uplift tube and an air line. I use them for Bristlenose and Cory eggs, work great.I use the kind of traps that hang on the front of the tank and use an airpump circulate tank water through the trap and back into the tank. Water quality is where they were born, should likely grow and is a lot cleaner being filtered. I think I have 6 or 7 of them.
