Shrimp and Planaria


So, I still have my planaria issue going on in the shrimp-mania and need some advice. I did a 35% water change yesterday and today a 15% because I saw a bunch of them in one corner and thought I will take that chance.

I know they came from overfeeding (not that easy to find the right amount) and since I use the blasting sand as a substrate, I can't really poke around in the substrate to stir it up and clean it thoroughly. I kinda touch up the surface of it and that way I can get some more out.

Now I know, using a dog dewormer is an option to get rid of them, but since there is a reason how they came, it kinda fights the situation, but doesn't fix the problem as I think they will reappear until I can figure out, what habitat of mine is causing them to be there in the first place.

Question: How can I take better care of the substrate to keep it cleaner? How many water changes are safe for the shrimp but effective enough to get rid of these planaria?

My maintenance is like a 10-20% water change biweekly. If that needs ti increase/decrease please let me know... I never changed the filter cartridge yet (tank has been running since July 2013) but I did "rinse" it in old water maybe about 3 times since then. The tank is a 20 gallon with a 75 gallon HOB. I use prime as a water conditioner and dose with Flourish comprehensive twice a week.

I feed about 2-3 a week half of a strip of the azoo food and fish flakes and other things, really small amounts... Too much?

Inhabitants are Red Cherry Shrimp, maybe all together about 40-60 I would guess, there are shrimplets everywhere and almost fully grown offspring.

I am happy about any suggestions

water changes wont do anything for removing/killing planaria.
there are a few different methods out there you can try.
1. being any of the various powders/etc that kill them.
2. a planaria trap if you dont wont to dose you water with chemicals.

Which one is most effective?

And it still leaves it open, how I do prevent it from happening again?

Can't stop it from happening again. But you can stop feeding too much. They hatch from cysts that are present everywhere

Suggestions to get rid of planaria? Safeguard or any other dewormer. Suggestions to keep them from coming back? Nothing you can do besides not overfeed.

Use repetitive doses of chemicals if you want to have the best shot at getting rid of them permanently. Otherwise reduce feeding and a planaria trap will control the population. You can also throw in some fishes/CPO to try to control the planaria population, but there will most likely be shrimp casualties if you do that.

Contrary to some beliefs, planaria must be introduced into a tank, it will never ever appear in your tank if they were not introduced into your tank. They don't come out from nowhere just because you overfeed, so make sure you are buying livestock from reliable and good sources, they are usually how planarias get into a tank.

Are you sure? The tank was cycling empty for 2 months when they appeared, only life plants in there but nothing out of tanks.

How would I dose the safeguard, how often and when a water change? Take carbon out in that time?

Thank you all for the help so far!

And do planaria kill mystery snails or other snails?

If you had plants in the tank when you cycled it them that's probably how planarias got in. I'm not sure if planarias will kill snails, but anything that kills planarias will kill snails. It's up to you to decide which to keep, and if you do decide to dose chemicals, you should monitor your ammonia very closely because there will be dead planaria/snail corpses around

Yes, you should take out carbon, I'm not sure about dosing safeguard, I've only had Planaria Zero, do some googling and you should have your answer

That's interesting, I tried Planaria Zero and lost the nerites... Doesn't these dewormers all work simiilar to each other?

No, they don't.

Fenbendazole is a dog dewormer. It works in dogs by dissolving the protective layer that normally prevents a worm from being digested. I assume it works similarly with planaria, by removing their ability to create a slime coat.

Snails also have a slime coat, but I'm thinking the devil is in the dosage. Planaria are tiny and we use tiny amount of dewormer (around 4 ppm). It seems to be enough to kill planaria while allowing most snails to function normally.

Betel nut extract functions as a stimulant and strong vasoconstrictor. I don't know if that's the function that kills small invertebrates, or if one of the other alkaloids or phytochemicals is just plain toxic, but it works to kill everything, including baby shrimp.

Fenbendazole won't kill baby shrimp even if used at double the dose suggested. I've heard of it killing nerites but have never seen that happen with my own eyes.

I see. Perhaps if in the future if I somehow introduce planarias I will use fenben. How about hydras? Are they equally susceptible to fenben?

Could you introduce a shrimp-friendly fish, even temporarily?
