My tank looks like it full of marine snow. I am not sure if it's a good or bad thing. I also have 5 or 6 tiny white worms flailing about in the water, they are maybe 1cm at most. My tank is plants only right now and it's been setup for 6-8 weeks. Should I be concerned?

That would most probably be Nematodes.

 

The ones in the picture are crawling on the glass ?

If that is the case, then those are Planaria.

 

Planaria and Nematodes are nothing to freak out about. They are harmless, only drawback is that they are unsightly when there are too many of them. 

They are commonly introduced into the tank by plants, or water from the shrimp/fish you bought. One reason you don't dump the whole contents of the bag from the store into your tank.

Or maybe this is an old tank that you used to house fish in and is now converted for something else. Old filter media could also be home to planaria and nematodes.

Planaria and Nematodes are present even in fish tanks, but the fish eat them, so you never see any. Use a fish if you have no shrimps in the tank. 

Planaria and Nematodes thrive when you overfeed. So cut back on feeding.

Water changes, including gravel/substrate vac can help reduce their numbers a little.

But if you are desperate, you can turn to chemical warfare -

  • Genchem No Planaria,  
  • Benibachi Planaria Zero,
  • Borneo Wild Exterminate, etc

will all work to get rid of them as fast as 1-2 days.

Use half the recommended dose, and do a followup dose a week later.

Perform water changes 2 days after each dose.

They never hang on the glass, they just wiggle around in the water. Someone suggested they were detritus. 

It's a brand new tank. Only thing it's ever had in it is plants.

What about all the tiny white stuff, I think they are organisms, floating around. Any idea what they might be?

Then they are nematodes. If the tank is new, then they would have hitched a ride in on plants. Or on the rocks. Where did you get the rocks from?

What substrate are you using by the way?

Not sure, unless I can see a very close up photo of it. It's either small nematodes or cyclops. 

In either case, it means the water conditions are good for them to thrive in, and with no predators, they multiply. 

My previous suggestions will still help. And with no inhabitants in the tank, it's easier to treat without worrying about harming anything. 

What you see floating in the water is probably only a quarter of them. The rest will be hiding in the substrate.

Get some of those products I mentioned above, or anything with Fenbendazole in it.

Treat the tank as per instructions and stir the gravel as much as possible. Yes it will mean your scape will be disturbed, but it also means you will get all of them, and minimise re-occurrence.

I am using Flourite Black Sand. The rocks are local, they have been sterilized by baking in the oven at 450 for 30 mins. 

Do I have to kill them? Are they going to hurt shrimp once I get them?

Also what are detritus?

Detritus just means rubbish, litter or waste. Sand, silt, organic matter from decomposition. But it doesn't look like detritus as it's all white in colour and have a similar shape (long, and thin).

They won't hurt shrimp. But now is the time to get rid of them if you don't like them. 

If you leave them in the tank, they will help break down detritus in the substrate. But they will also multiply more and be even more unsightly. 

It's really up to you and your choice.

Thanks. I am not sure what I am going to do but I will figure it out before I get shrimp.

Don't stress too much over it.

If you want a cheap solution,

  • Remove your plants
  • Drain 99% of the water, including the water in the filter/s.
  • Wash filter in the old tank water.
  • Pour hot boiling water on the substrate till it is all under hot water.
  • Drain and refill the tank.

I only suggest this since you have no inhabitants in the tank.

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.
