Planaria In Fish Tank

Planaria are small worms that live in aquariums. You’re probably not sure where they came from, but either way, you know you don’t want them and don’t like them. They look like this

Yours might not be pink (probably white) but it really depends on what it has been eating which defines what colour it is. The above planaria has probably eaten some coloured flake food (which they love).

Planaria appear in lots of different aquariums and often arrive in plants – but it’s very difficult to identify where they originate from. If you have fish in your aquarium, then you’re in luck as fish love them and snack readily on them (very satisfying to watch…).If you look at your tank closely, planaria move around on glass and in the substrate – they’re surprisingly fast too. They eat fish food (predominantly) and to a degree, can be controlled by ensuring you’re not feeding too much. I’ve also seen them eat snails, snail eggs, fish eggs, shrimp and so on. I’ve also seen one trying to eat the eggs of a pregnant cherry shrimp (fortunately she wriggled away).

Many hobbyists who keep aquariums without any fish but shrimp struggle to get rid of planaria once you’ve got them. No matter how many water changes you do and how clean the substrate is, it’s very hard to get rid of them until now. Genchem No Planaria is a unique powder that can be added safely to any aquarium with or without fish and is totally harmless to shrimp. It’s biodegradable and uses a natural product called Betal Nut Palm Extract. Dosage is very simple done over 3 days and we have used it in one of our shrimp tanks and no losses. Even the pregnant cherries were fine so we’re very confident in recommending this product to anyone.

If you have used this product, we would love your feedback.

  1. Great little write up. I’ve definitely got planaria in my shrimp tank and have been trying for ages to get rid of them. They’re really difficult to catch with a net – sometimes I use tweesers but they shrink up to nothing. You sure this No Planria is OK? I’m always worried about putting anything into my shrimp tanks cause they’re so sensitive.

    1. Yes it’s perfectly safe for use in a shrimp tank – you’ll have no problems providing your follow the instructions on the packet.

  2. Hi Vivienne

    I’m really sorry to hear you had problems. We sell a lot of this product, not only to shops but also to other customers. I have also used it myself and didn’t have any problems so I am surprised to hear what happened. I can only imagine it reacted with something in your tank, but you did the right thing with water changes.

  3. I can definitely recommend a device I tried in preference to chemicals for getting rid of snails. I make no apologies for buying the Snail Trap (£5.35) from Watermarque as I buy live crickets there for my reptiles.
    The trap is baited with the supplied pellets and lowered into the tank on the supplied length of fishing line.
    Results:- After 2 hours 40 snails caught and removed. Same time span – same result. Overnight – 200 snails.
    Nothing toxic and it works a treat
