Diamond Goby moves in

I have added a diamond goby to my tank, and could really use any advice from the masses regarding it's care. The LFS said it would be fine for my tank, and what I've read says he'll be a good addition too... but it's always good to get other's opinions.

Tank background: It's a 75 gal tank with a 20 gal sump/refugium. I run a coralife 125 superskimmer with varying degrees of success (the goby really set it off when he made his first few holes... but I have that under control). The tank has been running now for about four months... so it's not the most established tank out there. About 80 lbs of live rock. Water parameters are almost perfect. The sand bed is between 2 and 4 inches deep depending on where you're measuring. He's alread dug a few holes under well seated stable rocks. There seems to be plenty of pods in the sand, but that is one source of concern for me... how much is enough?

The LFS said that there was really nothing special to feed the guy and he'd either make it on scraps and what he could dig up or he wouldn't. Sounds "fishy" to me...

His tank mates are a dozen snails and hermit crabs (mexican), two blue neon gobies, and a juvenile auriga butterfly.

Question: I currently am filtering the water from the refugium through a 100micron filter sock for noise/bubble reduction. Should this sock be removed if I want the refugium to supply him with additional pods, or should I not worry about that?

Anything else I could benifit from knowing would be appritiated.
 
Mine is constantly cleaning the sand and readily consumes New Spectrum Pellets. He's big and fat also.

The Diamond Goby is a documented carpet surfer. Cover your aquarium.
Auriga/Threadfin Butterflyfish will pick at desirable inverts as well as Aiptasia. Not a good Butterfly for a reef aquarium.
 
My Diamond Goby just jumped out of tank today, did not survive. Surprised me because he spent all his time on the sand. HE was great for the tank, he kept the sand turned and clean. I will probably get another.
 
I've got eggcrate covering the top of the aquarium. I doubt he'll make it out... he'd have to be in just the right spot and jump just right. He might make it into the overflow box, but there's a screen over the drain, so he wont make it further than that.
 
The problem with this species, assuming you are referring to Valenciennea puellaris, is longevity. They tend to not survive in the long term for several reasons:

1. Malnutrition--they need quite a bit of sand infauna. Though they will feed on some zooplankton, their dietary needs are heavily skewed toward zoobenthic crustaceans.

2. Burrowing issues--be sure everything is well secured, because burrowing activities will undermine your rockwork.

3. Carpet surfing, as Gary said.

I am sorry your LFS did not give you the truth (or even know the truth). The main thing is to make sure it feeds on prepared foods and that you have an adequately conditioned and established sandbed, teeming with infauna.
 
I've got 2 and 3 covered well... the rock is very secure and there's only a few gaps in the eggcrate that it might make it through... but I think that they don't really plan their escape like maybe an octopus would. Malnutrition is what worries me the most. I'm going to give reef_doug's pellets a try as soon as I can find them. I found them on the net but paying $7 shipping on a $10 can of food seems wasteful.

Is there any strategies for increasing the zoobenthic crustaceans (pods... I assume) that you are refering to? I have a refugium with about an inch of sand in it, some live rock rubble and a ball of cheato. As I said, I have a filter on the outflow, beacuse the noise is too much for my living room if I just let it dump into my sump. Should I transfer sand from the sump to the refugium regularly, or will the zoobenthic crustaceans make it from the refugium to the tank without my help?
 
Thanks for the article. I don't think I made a bad choice. I'm running the tank FOWLR and was looking for something to clean the sand up... he's certainly moving it around. I'm still hoping for some feedback on my refugium set up.
