    I know there are a lot of goby fans on the site so I thought I’d post this. I’m in Costa Rica researching cichlids and a few days ago was at the Osa Peninsula in the Southwest of the country. I hit one river in the Osa called the Rio Barigones and snorkeled it. As I hit the water I noticed what appeared to be a river inside the river made of millions of little fish swimming up stream. I dipped my head in and saw they were little Sicydium gobies (.5-1 inch long). I believe these were making there way back up the river from the ocean as it’s not very far from the ocean at all. The video I have isn’t great and doesn’t due justice to the amount of Sicydium in the river, but you can get an idea of what it was like.

    Here are some photos of adult Sicydium salvini from the area

    Unfortunately not this year although I thought about it. Good news is they are extremely common throughout the area and would be easy to collect.

    My bad, I typed in the wrong species. I was on the Atlantic side of the country a few days ago and there you find S. adelum. On the Pacific, where the fish from this post are it is Sicydium salvini. Can a mod go in and change it in the title for me please so it reads Sicydium salvini Migration. I changed it to the proper species in the post.

    Matt, the fish in the photos are adults around 3.5 inches long. I believe they are females. I don’t have a photo of the male, but they are nice. They are larger and I’ve seen some 5-6 inches in length.Although not super colorful, the males are olive and have some spotting to them as the center of each scale has a dark spot. They are somewhat lighter ventrally. Males also develop nice extensions to their dorsal which is also a little lighter in color.

    I’m an undergraduate student doing work on breeding behavior and fry development on the cichlids of Central America. I’m in Costa Rica to gather some data and am towards the end of my near 3 week stay. It was just by chance I hit this river at the right time to see the migration.

    Glad everyone likes the video

    Thanks for the edit Matt.

    It’s a ton of fun, tiring but fun. I went last year and the weather was much better as far as doing fieldwork is concerned. I’m based at the La Selva field station for this trip and we got flooded out of our cabinas. It’s been lots of rain and for me, not many cichlids breeding due to the high waters and extremely swift currents. The gobies like it though. I’ve got more fish pics, including gobies, and other fish from the trip if people want to see them.

    theres a lot to be said about seeing fish in their natural surroundings as behavior will be so different to a tank set up
