    I saw this critter in my tank maybe 4 weeks ago, they barely move around, and they are very hard to get off the glass, they stick very well. I had one small guy stay on the same leaf for at least a week, did a good job on the algae. I noticed a bigger one down in the substrate a few days ago, and today he has popped up on the glass, again, barely moving around.

    Yey a freshwater limpet. They are truly good with algae but in my experience prefer harder water with little CO2. They are nice since they do not breed as much as snails.

    I’m interested to see how big they can get. My water is low on the KH side under 1 degree. I think they came from my pond when I brought a bunch of pond plants into my tank, or maybe a lake in haliburton when I tried growing Canadian pondweed.....life........finds a way.

    I just found something like this is my shrimp tank
    de26b93de0690789c1205b5345dbda3a.jpg

    All I have and it is neocaridina and that’s it it’s a 5 gallon Spec has some planira in the substrate.

    I also saw these in the tank two days ago on the glass of the tank, but the have since been eaten by a chilli rasbora in the tank. Somebody on skf said they are some type of shrimp parasite?

    Yes the first photo shows a limpet.

    The second picture seems to show copepods. They are not parasites. They do however compete with the shrimps for food. Boraras love them.

    The limpets won’t hurt the shrimp, they are like snails, you can leave them alone. You said you had planaria? The planaria will harm other livestock, in my experience, I’ve seen planaria kill fish/shrimp, granted I had a ton of planaria in that tank.

    A lot of folks that think they have Planaria actually have rabdocoel flatworms which are harmless. Only Planaria have the triangular heads.

    That’s what those were! I had those in my new tank. I was so paranoid they might be younger planaria, I started vacuuming these guys up. I wasn’t sure because they looked a bit like them, but no triangle head.
