Loach Goby (Rhyacichthys aspro)

So many interesting fish in these photos that I know next-to-nothing about!

@Summer Tanager I post new and obscure species for a reason, to generate interest and discussion. Thanks for the feedback!

@RatioTile Well, you're doing an excellent job! You have some great photographs and about half of your fish photos are of species I've never seen (and in most cases never heard of before!). Thank you for posting these - you've created quite a collection!
