On a recent road trip Char and I stopped off at the Oregon Coast Aquarium. Cool aquarium tunnels. Some snaps:
Pics of my 45g tank with two gravel eaters, 4 ruby barbs and 1 lovely bichir. Its a planted tank that needs some infill. I am going to drill holes in the main wood piece and fill it will trimmed Java fern to add height and shape. I would like to cover the “cave” wood piece to the left with baby sword growth eventually.
