    So I was watching my gobie remodel his house in the sand and he jumped on a rock and started eating algae. Is this normal or is he looking for food?

    Diamond Gobies typically do best in tanks with a smaller grain of sand than what you have. They are primarily sand sifters, he might be hungry for anything.

    I doubt that it's eating the algae, but rather sifting through it for pods.

    Actually the majority of the sand is pretty fine. He sifts all day long and the built up the spot in the video. He also brings the larger pieces of coral over and stacks them lol

    Ok, that makes sense. I think I'll order another couple bottles of pods, I still have plenty of phytoplankton left. I guess I should start harvesting pods and phyto so I have plenty to go around for everyone.

    Mine usually spreads the sand in the rocks even with the sandbed and then sifts what little sand is their. But they do have a tenancy to hunt for food.

    My thoughts as well. He probably isn't getting enough nutrition from your sandbed. I would suggest supplemental feeding.

    Will pods do or is there something else they really like?

    I agree, you need fine sand in there. That's way too coarse for a sifting goby. You need no bigger than Fiji pink, preferably oolite sized sand. I'd try target feeding him with some small mysis to make sure he's getting enough.

    I guess it depends on your refugium. Probably safe to feed mysis shrimp at least twice a week.

    "Fiji Pink" is .5-1.5mm in size; the sand in this members tank looks to fit that profile.

    Yeah I have Bimini Pink but he does sift pretty much all day though. There are larger (up to 5 mm) pieces of coral but it seems that most (probably 70% - 80%) is the finer grain sand. There are a lot of larger pieces in that clip cause he was going out and getting the larger pieces and putting them in front of his home. I do love my little Goby so I'll make sure to get him what he needs. For now I'm going to get a bunch of pods and I will try feeding him some Mysis tonight. Thanks for the advice!

    My diamond goby eats LRS like it's going out of style.

    My fuge is... 30G 3 compartment w/ heaters/skimmer in 1st, chaeto in 2nd, and return pump in 3rd.

    Would sifting out some of the larger pieces be worth it?

    Bikini pink is probably fine, I had a bag of that mixed with Fiji pink in an older tank. It had a lot of larger pieces but seemed to be about 80% Fiji pink sized. What I saw in the video much have been all the chunky pieces.

    Personally, I prefer super fine sand. I've got a .5mm black sand in my tank.

    Not in my opinion. I have some larger pieces mixed in with my sand and the goby uses them to shore up tunnels he digs on occasion. He'll meander across the tank to grab specific pieces sometimes.

    I really wanted black sand! This is my first tank though and I wasn't sure I'd like it or how it would look. I think that will be my choice on my next tank though.

    Yeah, mine was going all over the tank and getting the large pieces...weird? LOL

    I just got some LRS herbivore frenzy, he was eating some of that but it didn't seem like he ate a bunch. Maybe he'll eat it as I feed it more.
