Gobies

[Moogled]

Gobies and blennies will be fine in a barebottom tank, guaranteed.

The only possible exception is that there might be some sand sifting gobies that do need substrate. If anyone can confirm, that would be great.

In terms of a 14 gallon tank, you can opt for many choices such as:

Randall's Goby
Wheeler's Goby
Yellow Watchman Goby

These stay relatively small and are very docile. The Yellow Watchman goby in particular has alot of personality. I've seen pictures of one sitting on someone's hand.

If you want a larger goby-esque fish, a Lawnmower Blenny or Bi-Color would work. I've kept a lawnmower blenny but you don't want an algae eating competitor, especially in such a small tank.

That said, some gobies will fight with each other so keep that in mind when stocking more than one.
