The title says it. How are they? Active? Aggressive? Easy to keep? I'm looking for a blenny, but jawfish keep coming up. I've never had one, but i'm interested.

It's a fish only so I'm not worried about corals. I had a couple diamond gobies as well. They starve in tanks. In the wild they claim a 10x10 area.We struggled with jawfish until the last 2 that we got. We really wanted the diamond spot variety but did not have success so tried yellow-head jawfish. We have two of these and they are fun to watch - very, very active. But they have completely re-scaped the sand in the tank. Unbelievable how much sand the two of them can move in a few hours. They also decorate the entrance to their burrows with snails. These two have paired so they are always together.
I would say the negative to them is that they drop sand all over the corals and rock flower anemones in the lower half of the tank. My husband takes a baster and blows the sand off at least once a day and always before we spot feed the corals. Don't know if that is being obsessive but that is his thing.
The positive is our sand is very clean! When we use the Python siphon pipe to clean the sand with the monthly water change there is definitely way less detritus than there used to be.
Here is a photo of the sand bed that they re-arranged from flat to hilly in a few hours. All the sand above the rock flower was not there before they decided to go all HGTV on their burrow! The arrow points to their burrow.
