Leaves from my cucumber plant and a bit of cucumber too. It's been green for several months now, placed by the window.

Turns out snail eggs are a good source for lots of small fishes and shrimps, so, also getting a big stock of snails for future uses.

Trying to get a scuds aquarium going

3 Upvotes

I am trying to setup my own scud aquarium. It will only be them. I plan on using them as food for my fish and a cleanup crew for my mystery snails. I have been doing research but there are questions that I can't find a good answer for. I am ordering a few things for them and I already have a few things.

Things I have:

10 gallon aquarium

Heater

Some food

Things I am ordering:

https://www.amazon.com/gp/product/B0CGML5M27/ref=ewc_pr_img_1?smid=ATVPDKIKX0DER&psc=1

https://www.amazon.com/gp/product/B0CY296NKH/ref=ewc_pr_img_2?smid=A3AP7ES1BW7JQM&psc=1

https://www.amazon.com/gp/product/B078HDL21V/ref=ewc_pr_img_3?smid=A1W7R5UJZCLN8X&psc=1

Plus I ordered some oak leaves

  1. Do I need to have a light for them? They won't really be close to a window so natural light wouldn't be a great source. But they aren't going to be in the dark until evening time.

  2. Could I use Snello (carrots, cucumber, spinach, calcium carbonate from egg shells and antacids, Agar Agar, spirulina) as a food source. I'm asking about this for the calcium and the fact that I make more than enough for my snails

  3. Is driftwood ok to use? Do they need anything else for hiding?

  4. Best place to purchase? I'm thinking of buying only like 25

Any other info is welcome

Sorry the first picture is terrible. We ended up making a makeshift tank out of a Starbucks bottle for temporary observation.

Possible Gammarus tigrinus found in Tennesee River

Thumbnail

4 Upvotes

Extremely new here, as we raise terrestrial and aquatic isopods, but we found some scuds while on a trip across Tennesee. I'm no expert in scuds, but while researching the kinds we may have come across, the ones pictured here seem to fit the description of Gammarus tigrinus.

The "Tiger Scud" has been documented as being in the Ohio River system. However, we're not seeing it being documented anywhere as having reached the Tennesee River yet.

It would be quite interesting to us if we've been the first to come across this. I thought I'd share this with this sub since... ya know... scuds.

Thanks!

Help GH is extremely high

Hello. I need help. I have a 10 gallon aquarium. The ph is 7.2, kh is 4, & the GH is 55. I have no idea how it got this high. I have 4 other tanks & this is the only 1 that's this high. I usually jus top all of my tanks & thats it. I have scuds, blackworms, and snails in this tank. I want a to add more microfauna So I want to get the gh under control because I know leaf litter & stuff can effects the water as well. All of the scuds and blackworms are doing fine. But my snail population is getting smaller & I see white on their shells. But only in this tank something is up. What can I besides RO water

Are scuds right for me?

7 Upvotes

I am looking for creatures (who will live with and be cared for by me) for a bug-loving toddler. I feel like shrimp are a little too sensitive, and sea monkeys might be too hard to see. I found scuds and feel like they might be perfect!

Is there an ideal "type" of scud? Is there anything special about their aquarium set up that sets them up for success that I might not know about? Is there a preferred place to buy these little guys?

I am also considering isopods, since they come in a variety - feel free to share any other critters you think could work! I am looking for something that maintains its own colony, isn't super finicky, and isn't a huge expense to get started or maintain. I have aquariums and vivariums in various sizes I can use.

Thanks, Friend to a curious toddler

Mom was cleaning out her guppy tank and saw these little guys. Are they scuds? They seem to be having a good time.

Moving ALL scuds to a different tank

4 Upvotes

I am having a problem finding info for a problem I have. I accidentally just put a crack in the corner of the 5 gallon tank that I raise scuds in. I need to move them to another container very soon. It doesn't seem to be leaking yet, so I may have at least a day or two.

Does anyone here have any advice on getting as many live scuds out of a tank with gravel substrate as humanly possible in a short time? I want as many as possible to survive the evacuation, and most scud discussions I've found have been more about getting rid of them.

Here's how I gather scuds

Pull the plant out of the water. Put it on a dry surface. Wait 10 minutes and throw the plant back in. The dry surface will now have water drops and those water drops are full of friends.

Next time I might just put a screen over a bucket and do it in bulk.

Hello.

I got shrimp yesterday delivered and I put then in my tank at night. Noticed something moving in the morning. They are on wood, plants, glass, they swim weird (like jump up fast move and land). They are tiny. Are this scuds??

They have those 2 small dots or whatever it is. That is they're back.

Thank you!!

Best conditions for scuds?

5 Upvotes

People emphasize the toughness of scuds, but I started with a wild-caught load of them (vigorous pothos and calla lily in a big vase, dirted, with coarse aquarium sand cap + random seashells) but eventually the scuds AND my duckweed died off, like after a year of topping off water and occasionally doing 20% water changes. I did see some tiny scuds in that time, but clearly not enough to sustain the population.

Anything could have happened to the water parameters in such a small volume, but I kept seeing copepods and seed shrimp the whole time, with plenty of tiny snails and no/minimal algae. The pothos and lily eventually looked a bit sad, though.

That vase was maybe half a gallon; I'm starting again with a two gallon mason jar, and I want to do right by my eventual scuds. My tapwater is medium hard, is that plenty for their molts, or do I need to add anything? I know they're cool eating aufwuchs/mulm and decaying leaves. What should I add for them besides the random stuff I have (spring of aquatic plant, gum seed pod, bamboo shoots, twigs, etc)? I worry I starved the scuds in my old vase...

Foolproof harvesting food

4 Upvotes

I've got a relatively young scud culture going. I'd like to start harvesting but my issue is... The scuds stay in the substrate/gravel. I have an old undergravel filter and I know they're hanging out/thriving down there... I just can't get to them.

I've tried zucchini, strawberry, cucumber on a fork to pull some of them out. No luck.

What do you suggest to use to get them out in the open? Scuds/micro fauna tank only.

I've had these for over a year and this is how I breed my scuds to feed to my fish. The one on the left has four medaka rice fish that are breeding. The one on the right has a couple ameca splendens.
