ok I added My two main Bristlenose to the new tank today and boy was it hard trying to catch them. In the end I had to fool them by putting their cucumber food inside the fish net in order to trick them. Anyway after a bit of exploring they finaly found the peice of bogwood i put in there for them to nibble on. The wood took a bit to find becouse it also has a slight hollow underneath forming a cave and anouther place for them to hide in.
The male soon found this hollow and has been busy digging diff ways to enter it and it seems the female has also found this prime peice of realestate and wants to share with him. Here is a short vid of them "playing" in and out of the bogwood cave
