Mr. Goby's Wild Ride

Although what that ride was, I'm not sure ... Here's the backstory:

I picked up a diamond goby (from YourReef -- plug, plug :)) a while back. The day after I added him to the display I was due for a tank cleaning/water change. Somewhere during the process he ended up in the overflow, which has a screen that extends 4" above the surface to prevent just this type of event from happening.

Of course, the overflow is deep and congested with pipes (closed loop drain, open loop returns, stockman standpipe, pvc conduit for electrical -- you get the idea.) I had no idea how I was going to get this skittish little goby out w/o totally traumatizing him, so I thought I'd just let him hang out and maybe he'd jump back at some point. The overflow has sort of morphed into a kind of refugium with ample supplies of crustaceans so I thought "what's the harm?"

Two days later he was gone. Spent the next two weeks examining the overflow, peering into the main tank rock-work at all hours of the day and night -- no sign.

Three days ago I saw him poke his head out of the rock work during feeding time and I've had no problem locating him since. Oh, and he's missing an eye, but other than that seems none the worse for wear.

There are four ways to get from the overflow back to main tank:

1) Jumping back over the screen

2) Down the stockman pipe, into the sump, pumped back through the Mag7 return. Never saw him in the sump, and although I've heard of fish surviving the impeller, I'm not convinced he could fit through the plastic strainer on the pump intake.

3) Via the closed loop, but he would have to pass both through an Iwaki pump (actually the impeller looks pretty passable for a small creature) and through a chiller and my guess is that the passages through the cooling elements are pretty darned narrow, so probably not likely. Plus I think his skull is larger than the 1/4" holes in the spray bar on the return.

4) I have a manifold to create flow in the main tank which uses a Rio pump (I know, I know ...) hanging in the top of the overflow for its source.

Of course there's no way to know, but what are your votes for the most likely return path? Given the missing eye, I'm squeamishly leaning toward #4, but I don't know. And two weeks MIA? Must have been hiding somewhere recovering.

Oh, yeah, there's nothing even the remotest bit agressive in the tank (yellow tang, 2 pjs, chalk bass, randall's goby, pep shrimp/cleaner shrimp), so I don't believe any body bit his eye. No inidications of any kind of a mantis shrimp.
 
Wow! Sounds like only God and Mr.Goby know the answer to that one:Dheheh whata trip!Litterally!

I would be very surprise if you goby can survive through any pump. My guess - he jumped back into the tank. :D

Is the top of the screening sharp? Someone was giving away overflow mesh at the may meeting and after I cut it it was very sharp at the top. He may have jumped over and cut himself on the mesh.
 
I suppose that's possible -- it's just that black, nylon mesh like you get at HD or OSH, 1/4" mesh, I think, but the cut ends are raw.
 
At least your diamond goby lasted longer than my diamond goby. I bought mine from YourReef, and it committed suicide the same day. :P

Glad your goby made it through. How do you like him? I am debating getting another one.

I like that he's still alive :) I had visions of him stuck in the chiller somewhere, slowly disintegrating ...

Honestly, I didn't get him for looks -- I liked the way John's kept the top of his sand stirred up; got him for that reason.

Both my gobies are pretty shy. The diamond found a place where if you get right up next to the glass in a certain spot and peer down through the rocks, well, you MIGHT get a glimpse of him. He does dart in and out at feeding time. My Randall's goby -- which I did get for looks -- is out a little more often, but if you get too close to the tank he hides. He spends a fair amount of time perched on the mantle of my crocea clam. Now THAT I find interesting because that clam pulls in if anything gets anywhere near him, stirs up the water, whatever -- but it totally ignores the goby, letting him rest in direct contact with the mantle.
 
Minh, it probalby was just a single incident with your goby. I still have mine so far, I have seen it swim mid water level, but never to the top they are great to have. You should get another one.

bsaastad, Wow thats insane. Atleast he is still alive, must suck with one eye, but id rather be alive. Id say he jumped back in.

Apparently not, seeing how this thread is here ;)

LOL... thanks I was dead tired when I made that reply. I got 4 hours of sleep the night before, So I was running on fumes....

What i was meaning was that maybe if he got another, it wont happen again....:-P
 
Too cool....at least he made it back in (mostly) one piece ! lol

How much sand do they move around ? I'd like to get a sand sifting goby, but am hesitant as I don't want sand in all my corals that are lower down on or near the sand.
 
As with all fish it depends, another thing is there size. I have a fairly small goby and he doesn't sift too much around at one time, but he keeps my top sand sifted for the most part. The larger the mouth the more displacement it will do, along with moving rocks and such. When I see mine sifting it does it down at the bottom and it spits the sand right back out thru its gills.

Only time I had sand in the water column is when he was trying to make his burrow home.
 
I've had fairly large amphipods make it through the impeller of my mag 9.5 and smack the glass, then scurry off as if nothing had happened. Timing, and a body shorter than the gap between blades, has to help one's chances. If he got through the impeller, he probably jammed the pump and wriggled through, losing bits in the process---and jamming these little plastic impellers is not that impossible.
 
Sk8r - there's a huge size difference between a small goby and a large amphipods. I can believe that an amphipods will make it through a mag 9.5 impeller. But a diamond goby though a Mag 7? I doubt it. :D

Edwin - does your goby sift just one spot or does it sift throughout the whole tank?
 
Minh- Most of the time He is sifting thru the whole bed in different spots and on other days he just hides under a big rock.
 
Well, I finally got a good look at Mr. Goby's face. Sorry, no pics -- the only way I can see him is if I feed the tank, then stand absolutely still where I can see his den and wait for him to come out. Any motion and he's gone. Anyway ...

I was willing to think he snagged his eye on the screen jumping back out of the overflow, but the whole right side of his head is mangled. The side of his skull is caved in a bit behind where the eye was, and looks like a patch of skin about 1/4" high by 3/8" long was taken away and healed over. No pigment or coloration is present in that area; doesn't match the other side of his head at all, which has the little bluish flecks on the side of his head. I'm starting to lean back toward one of the impellers. Ouch.
 
I finally got a picture of him. You can see the eye is completely gone and there's a serious scuffed patch down the side of his head -- don't know if you can really make it out here or not.

well I know your pain... My goby is MIA... I havent seen him in many weeks. I dont know if he jumped...BUt hes no where to be found and i cant find a body, But I am having a nitrate spike, so i think something happened to him in the tank and he may of crawled under a rock and took a deep sleep.

:-(
