Wildlife World Zoo & Aquarium
These small (only 3 to 4 inches long) fish were fascinating to watch, poking their heads in and out of their "burrows". The Wikipedia page does not tell us a lot, except interesting to note, the males carry the eggs in their mouths till the young hatch.
Note: auto-correct was used to remove the very green tint to these photos, a bit of sharpening was also done to crisp up the edges. They moved fairly quickly and being so small, they were a challenge to capture at all. They were entertaining to watch.
