I have a 10 gallon filtered and has pea gravel and I took all the fish out so I could move it when I realised there were hundreds of tiny crayfish looking creatures about the size of a grain of rice swimming all over they came out of the gravel! Their cute but what are they and will they hurt my fish?
Never had any kind of shrimp in that tank. I've been trying to get a clear pic this whole time they look exactly like crayfish they have a thick torso with little antennae and a long tail that has loads of tiny little legs the only thing I can't see is any sort of pinsirs or claws and they are a gray color
They are litterally the size of a large grain of rice
The gravel has been in that tank for over a year now and I had added a live plant about 6 months back but my snails ate it the last time I took the whole tank down and cleaned everything was 3 months ago and they most definately weren't in there and neither was any kind of live plant added
