Goo Obo Gudgeon

May 12th, 2008

Across two months of GWAPA meetings, I brought home four Goo Obo Gudgeons from the auctions. The Goo Obo Gudgeon is a small unidentified fish that was collected at Goo-Obo Falls in Papua New Guinea. According to the documentation that I got from the seller, while unidentified, this is probably either Allomogurnda or Mogurnda nesolepis.

When I brought home the first pair, I was admittedly a little bit disappointed. Shortly after adding them to my 54G tank, they disappeared into the hardscape, and weren’t seen for at least another week. Eventually, I started noticing them, hiding in the shadows underneath large anubias or cryptocoryne leaves, or between pieces of wood and rocks.

That’s when I decided to try adding 2 more to the tank, in hope that with four total, I’d see one of them more often. Fortunately, this strategy seems to have worked. Also, I started feeding the tank blackworms, which has definitely drawn them out of their hiding places!

According to the Baensch Aquarium Atlas Vol. 4, these gudgeons “inhabit small, frequently swift-flowing, gravel to mud-bottomed rain forest streams.” They also enjoy the cover of vegetation and plant roots, which exactly what I’ve experienced in my tank.

As young fish, they were not very attractive, but since feeding them blackworms, they have increased in size (max about 3″), and have definitely gone from rather drab looking to fairly colorful with bright yellow fins. I doubt that they will be able to successfully raise any young in this tank due to some very active catfish, but they’re very interesting fish to keep. (And they’re great additions for rainbowfish themed tanks.)
