jawfish saga

I have a yellowhead jawfish (name: GIJoe) that has not ever been happy for longer than a month at a time. Now I'm starting to become worried about his health.

I bought him mail order about 8 months ago. Well, when he arrived the box was way too cold inside. After acclimation, he lay on the bottom of the tank all night, curled up and barely breathing.

In the morning he was gone. About 3 weeks later, I tried another jawfish (name: Pvt Ryan), who worked out perfectly. He built a bunker exactly where I thought he would, under one of the rock structures.

Two weeks later, GIJoe shows up alive! He not only is alive, he's back with a vengence. He makes a complete mess of my tank, sand everywhere, and doesn't dig under a rock. Instead he digs right in the middle of the bed, and obviously isn't getting anywhere.

I move some larger rocks in the middle so he has something to dig under and he's fine for about a month. (never mind that he's jumped into the overflow 3 times by now) After a month, he creates another mess, jumps into the overflow a few more times.

I decide to move him out of there to my hospital tank. I have two seahorses the 46, and he's just disturbing them way too much. So I put the appropriate substrate in the hospital tank, and he's been there for about 5 months, with the same behavior. He's good for a month, builds a home, then devistates the tank looking for another home.

For the past 2 weeks, he's not moved back into his bunkers, and he's starting to look ragged His color is fading and his fins are ragged :( I don't know what to do for him

Params are all fine. The hospital tank is only a 10-gal, and it's downstairs where there is very little traffic at all. Could he be lonely?

Any suggestions?

:hmm1:
 
Not really. He's not as fat as the other jawfish, but he doesn't look underfed. Although the last few days, he's even afraid of his food when it drops in the tank, so I'm sure he's going to soon be thin :-(
 
Oh - I was going to suggest that he might have an internal parasite that is competing for his food - they can be so easy to treat, that if it's suspected, it's worth a little medicine.

FWIW, I have seen flighty jawfish like this - but unfortunately have no answer :(
 
Have you tried giving him an artificial hiding place in the hospital tank, like a piece of PVC? It might make him feel more secure.

IME when a jawfish wants to build in the middle of the sandbed, you can help them a LOT by giving them lots of pebbly-sized bits to help build it. I bought a 20lb bag of "puka shell" sand, that was mostly small shells and pebbles. I would rinse a cup of this stuff and gently pour some a couple inches from the burrow site. After panicking for a few seconds from the scary hand and cup, my jaw would have a great time picking out the best bits of shell and pebble to make his burrow. When the pile ran out, I would give him another cups worth. Using these materials they can build a solid burrow even right in the middle of the sandbed.

Try the pipe in the tank though (just set it atop the sandbed) - if he is too freaked out to build and that is stressing him to death, this might give him a temporary haven to get some strength back.

Good luck! I love jawfish, hope yours pulls through (again!).

Jayo, thanks for the ideas.

Yes, I've given him an artificial home. I hadn't thought of a PVC pipe, though, that would have been easier. I constructed a burrow out of plexiglass with a top and four legs. I even coated the entire thing in sand and pebbles, so he would think it was real. He lived there for a while, now he won't go near it :-(

In the hospital tank, I've done the same thing you suggested, and threw in a lot of small pieces of rubble. He uses them within a few minutes and builds a new home, but abandons it after a short time.

I just checked on him, and he's hiding under one of the frilly mushrooms that's in there, with his two homes sitting empty :(

Would he be bother by bristle worms or small blue-leg crabs, btw? I noticed just now that there are BW in his old home.
 
Yeah, the worms and crabs could be bothering him... But what can you do about it? It sounds like you are already doing all the right things. Hope things turn around and he pulls through.

Cinnamongirl, the only thing I can think of that you might not be doing is providing him with a large open area. Jaws like to be somewhat away from the reef in an open area where they have a nice long view of flat sand 360 degrees around the burrow - I suppose being forced to be so close to the rocks could bother some more than others...

Also , in case you didn't know, they are v-e-r-y sensitive to sudden on/off of the lights. He could be looking for a burrow where he doesn't get "freaked out" every night when the lights go out or something like that. It really can upset them.

Moonlights on your tank, if you don't have them (like 2 LED's) - if you do have them maybe he's getting too much light or something....

Just trying to come up with ideas - probably long shots though
 
I have a light-sensitive nightlight plugged into an outlet next to the tank, that stays on when lights are out. I've gone in the room during lights out and he's always in the corner staring at the nightlight. I thought maybe that was the problem, so I moved it across the room a week or so ago.

I know jawfish are people-watchers. My hospital tank is in the basement with my sump and other equipment. Could he be lonely? I really only go down there once or twice a day to check my systems or feed. Maybe he's lonely and overly freaked when he sees me?

Sounds like you've got all your bases covered - Like I said I've seen this before :( I once had one that was 'flighty" just like yours. Probably the best thing you can do is keep his situation as stable as possible for as long as possible and see how he does with that. I assume you've got the tank well-covered -- maybe some of these fish get flighty due to brain damage from jumping, hitting a barrier and knocking themselves out - only half kidding

If you want another fish maybe some mild mannered dither fish like a disease-free (good luck) blue-green chromis would be good for him - I wish I knew

Somebody else is bound to have some knowledge about this, but they're probably out partying as it is the weekend - lol

U have 2 jawfish in there right now?

No, there's one stable :cool: jawfish in the 46g seahorse tank and one flighty :crazy1: jawfish in the 10g downstairs.
