Pico Livestock

Looking for input on fish for a 2.5g pico. It is currently set up and running with a trio of sexy shrimp and a couple misc. frags, but I am itching for a swimmer Filtration is your standard HOB for carbon/floss and a 28oz water change every 3 days. CUC is a lone nassarius, two astrea and a pair of tiny blue-legged hermits.

Want to keep it to a lone specimen because of the obviously tiny size, preferably something that could stay the long haul. Being compatible with tiny shrimp is pretty mandatory as well

So far my thoughts are:
Stongobiops nematodes- hi-fin banded goby
Trimma cana- candycane pygmy goby
Trimma rubromaculatus- red splash pygmy goby

I had kicked around a yasha but ruled it out due to cost, buggers are expensive. For a fallback there is always some sort of clown goby, but outside the box is good

very cool fish..

 

Neat fish, was thinking about them but decided against it. Was looking for something that would hopefully be a bit more visible

 

dude the personallity is off the wall. Cool fish. I would do one of these and a flaming prawn goby (yes they are expensive)

 

Not disagreeing, the barnacle gobies are pretty nutty. The problem I have with the flaming prawn is the same one with the yasha...hard to bite the bullet on a $100+ fish that doesn't get much larger then an inch or two and costs more then I have invested in the entire setup

 

Gobiodon Citrinus-Citron Goby
Lythrypnus Dalli-Catalina Goby
Valencienna Puellaris-Spotted Sleeper Goby
Gobiosoma Oceanops-Neon Goby

Possibly:

Monacanthus Tuckeri-Slender Filefish

Would be pushing it but they get 3.5" max and are really unique.

 

Citron is one of the clowns I was trying to avoid but may wind up going with anyways
The catalina is off the list. They are a colder-water species and tend to do very poorly in our warmer reef tanks. I had looked at the diamond goby but don't they get to be like 4"ish?

The neons were another on the list but I was unsure if keeping one in such cramped quarters would be fair to it.

 

The flaming prawn goby is awesome. Where can one go about ordering one of these...
