Some eventually hitched a ride into my newer 55 gallon shrimp tank and they breed like crazy so I now have a ridiculous amount of scuds now. I have not been able to prove that my puffers, guppies or bettas eat them so at this point they are just weird tiny little creatures flying around my shrimp tanks and hogging all the shrimp food. The only annoying thing is that they are so tiny and so plentiful that you can’t really have them in a tank that has any filter besides a sponge filter because they will get sucked into the other filters and then you have to figure out how to save their lives when you’re cleaning your filter. Original review: I didn't count them obviously but they were all alive and there were some detritus worms as well which is a bonus. If I could do anything different I would order more especially if you're getting these to put in a tank with livestock that would eat them (puffers, guppies, etc.). I love how active and fast they are. I know they act as a clean up crew and I kinda like their appearance more than all the bladder snails that clean up tanks. I made sure to have lots of plants, moss and places for them to hide so hopeful they can escape all the predators in my tanks and still do their clean up job. They're definitely the most expensive aquatic livestock I've ever bought so I definitely hope they can escape the fish. They are obvious to spot in a tank, not small like copepods. Expensive but I'll probably order again and just keep them in their own nano tank because having them in a tank with established other fish is stressful, I did a water change and siphoned the substrate and had to net them out. It arrived faster than the original estimate. Review: Good quality - All alive after two weeks. Scuds arrived alive. We are two weeks into culturing, and one water change in. Have them in 4 gallons of water with low flow sponge filter, boiled India almond leaves, bio balls with starter bacteria, and feeding them shrimp pellets. They are all alive and seem to be thriving. The order arrived early, and I was out of town, so the scuds spent a few days in packaging at the post office but have done fine. ## Features - SHIPPING ALERT: If your local temp is below 35 or above 85 degrees F your package will ship "HOLD FOR PICK UP" at your local post office.

We are two weeks into culturing, and one water change in. Have them in 4 gallons of water with low flow sponge filter, boiled India almond leaves, bio balls with starter bacteria, and feeding them shrimp pellets. They are all alive and seem to be thriving. The order arrived early, and I was out of town, so the scuds spent a few days in packaging at the post office but have done fine. ### ⭐⭐⭐⭐⭐ Enough Scuds Arrived *by C***R on February 22, 2026* Many arrived dead, you can see in the photo that the bag has many dead scuds at the bottom. However, I still give it 5 stars, there are more than enough to make my own colony. The seller was meticulous and thorough with their packaging. The plastic bag they arrived in was made of material that allows the water to breathe, while not leaking. That bag was placed within a ziplock, then surrounded with paper, at the bottom was I believe a handwarmer, this was all within a insulated foil bubble wrap box. I honestly do not believe the seller could have done anything more to prevent the scuds that died during transit. I deposited some to my 75 gallon aquarium and the rest is in a 3 gallon tank to start my own colony. The ones that are alive are alive and seem to be thriving. Overall I am happy with my purchase. ## Frequently Bought Together - Critters Direct Live Freshwater Scuds (gammarus, sp) Qty-100 - ***New*** 15 Baby Live Freshwater Clams: Perfect for Aquariums and Ponds Brown, Gold, Tan, Silver 1 Count (Pack of 15) - 9+ Live Ramshorn Snails Aquarium or Pond, Algae Clean Up!
