White worms in tank - Planaria or Detrius Worms??
A common question....here goes
Fishy Fishy posted here a years or so ago with regards to new evidence relating to Planaria and ?worms? in tanks, which has now been accepted in fishkeeping circles ? yay, she got there first.
Firstly, wise to check if these are actually Planaria (the more leechy-looking ones) or just Detritus Worms (the thread-looking ones that wriggle in the water and about 2-6mm long).
Clip from Youtube, this guy has both. The first thin white wriggler you see first is a Detritus Worm, the two that look more slug like and squat, although zipping round fairly fast, are Planaria (babies).
Detritus worms feed of decomposing matter and whilst no threat to fish or tank inhabitants, they would indicate over feeding or lack of tank husbandry. Good tank, filter, substrate cleans and watching overfeeding should resolve the issue ? no other action. Indeed fish will eat them with relish once spotted.
Planaria though, are small flatworms and are carnivorous and their diet includes foods such as insect larvae, small crustaceans, fish eggs, other small living or dead tank mates and mostly arrive with plants. They can take on a fully grown snail/shrimp or a weakened fish and their presence is not related to dirty tanks.
The US favours a Planaria treatment called ?Clout? although I don?t think it can be bought in the UK ? see Ebay.com. Some treatments can knock out filter bacteria so it?s not a choice taken lightly as some planning needs to be undertaken first.
A quick look on google shows the following treatments used in the US:
Removal (Treatment) of Planaria:
There are several remedies that can rid a tank of Planaria, here are a few:
*Clout; this is probably the most effective treatment which contains 4-[p-(dimethylamino)-)O-Phenylbenzylidene]-2,5-cyclohexadien-1-xylidene dimethylammonium chloride; dimethyl (2,2,2-trichloro-1-hydroxy-ehtel) phosphonate; 1,2-dimmethyl-5 nitromidazole and inert ingredients as non toxic binders. A negative of this treatment is it cannot be used with Piranhas, Metynnis species, scalelesss fish, bottom feeders, Marine Sharks, or Lion Fish
*General Cure; Not as strong, but still often effective and less harsh on delicate fish. General Cure contains Metronidazole & Praziquantel
*Jungle Parasite Clear; As with General Cure, not as strong as Clout, but still often effective and less harsh on delicate fish.
*Most Medications/Treatments that contain Trichlorfon (although this is very harsh on silver fish, arowana, and similar) *Copper at .25 ppm can be effective for Planaria
FK can take no responsibility for these USA treatments of course. Posted here for keepers info only and I would assume personal research is undertaken first.
