I have a yellowhead Jawfish which I think is great. He made a great cave around and under one of the rocks towards the back of the tank which has a fairly complicated setup. He has a front and rear access and used the hole in a rock to help with the tunnel. I was worried about food floating back his way but we worked something out. After three days he's now more than willing to come and get it! I used my cellphone to capture a short video if anyone wants to see. That evening I was feeding some mysis.
