Hey all,

So I just picked up Blue Dot Jawfish (BDJ) and I was just wondering if there was anyone whose kept these guys who had any tips.

I am aware that these guys do like colder temperatures, but I also keep coral (LPS and softies) in the tank, I figured I could gradually drop the temp down to 75 over the next 2 weeks and that could be a good median between the corals in the BDJ?

Also LiveAquaria suggests feeding them 3 times a day. Is this necessary? It seems excessive.

I also have made sure to secure my lid and give him plenty of substrate around his den to mess around with (between 4-5 inches) although some places suggest 8+ inches of substrate, but do I really need that much?

I am also aware that they don't tend to do as well in captivity, but I made the mistake of purchasing and then researching (drawbacks of being an impulsive buyer) and I wanna do my best to care for this guy.

But yeah if anyone has any tips for a new BDJ keeper, I'm all ears!

I keep my tank at about 77-78, but cooler is supposedly better for these guys. I would say there are a few factors that I feel are the most important: 1) Deep enough sandbed (I'd say 3 inches is minimum) with rubble, shells, etc. so that he can make his burrow, 2) Tight lid in case he decides to jump (which is very possible before he settles down and creates his burrow), and 3) Introduction before intimidating fish- active swimmers like tangs, or similar fish that might compete for territories like some blennies.

I've only fed two times per day, and that is sufficient. They are not overly active and seem to hold their weight well with two feedings of quality frozen or pellets (or both).

One thing to note, your whole tank doesn't need a deep sandbed. I've created an optimal environment in one corner of my tank, and that is the only area I've built up the sand.

Good luck!

If you’re worried about the temp and corals, I have a friend that has some deep water butterflies and keeps his tank at 73ish and corals do fine. Probably not great growth but fine

id also look into blue spot jawfish disease, it’s a bacterial issue that might occur

Great point. I QT all of my fish, but the BSJF is definitely one that helps to QT first.

Thanks for the info! Yeah I had a raised sandbed area for him about 4 inches or so, but he relocated to a different corner of the tank with a shallow sandbed.

I didn't know why he moved until I saw my ruby crab poking his head out of the BDJF's den.

Okay that's reassuring, I'm hoping if I do a gradual enough drop I can get the temp down to around 73-74 without killing them all and I'll be sure to watch out for that disease, much thanks!
