I want to get a jawfish but I have never had any experience with them. I have a 180 gallon fish tank with a 5" sand bed. I was thinking of getting either a yellow head jawfish, dusky jawfish or a black cap jawfish. Anybody have any experience with any of these. Or can I keep all three of them in my tank? I want to have a peaceful jawfish since I have peaceful fishes in my tank. Any advice would be helpful thanks in advance.
