The weather here has finally improved to the point that I was able to order some gammarus shrimp (a.k.a. "scuds") and get them in the tank I had set up for them. I ordered the shrimp from Fish Gobble. I’m pretty pleased with the service offered by the website: I ordered the shrimp on a Friday and received them the next Thursday. They arrived in a rigid plastic container with a tight fitting lid (taped securely in place), wrapped in several layers of bubble wrap and mailed in a standard corrugated cardboard shipping box. The website sells them in 8-ounce quantities, measured by the 8 ounces of water they are shipped in. The water had a fairly thick layer of on the bottom and was pretty murky, which I kind of expected — these shrimp feed on microorganisms, and I’d think that a layer of would be a good place for them to forage.
When I first got the package I wasn’t sure how many shrimp were inside, but I could definitely see some other invertebrates scooting around. As I acclimated the shrimp to the tank I realized that there were actually several shrimp in there — probably at least a dozen — along with a large amount of what I think must be daphnia, copepods, and other . I definitely don’t mind getting a mix of critters… it’s just value added, in my opinion.
I followed standard acclimation procedures, gradually adding tank water to the shrimp container until I felt it was safe to release them into the tank. I dumped all of the shipping water andinto the tank, feeling that I would rather risk some type of contamination than lose any shrimp larvae, daphnia, or other .
The shrimp are barely visible now. I know that they’re rooting around in the substrate — a mixture of black sand and organic potting soil — and I’m hoping that they’ll find enough to eat and begin breeding. I want to be able to supply my other tanks with live gammarus snacks.
I’m really excited to have an inverts-only tank, and I’m definitely willing to buy from Fish Gobble again.
