Toying with the idea of another fish in 2.7g

[Draco]

I have a 2.7g cube set up here at work with an aquaclear 50 filter as a refugium.

 

I presently have a peppermint shrimp and a Yellow Clown Goby.

 

I am toying with the idea of adding another fish.. my options I am considering are:

Green Clown Goby

Red Striped Goby

Red Spotted Goby

 

all above stays around 1".

 

Bad idea to add another fish?

I guess its it's really up to you. Most people would keep 0 fish in a pico that size.

There are some species so small their bioload is equivalent to a shrimp. But even then you have to be careful, especially with territory and the inherent instability with pico systems.
