I found this weird thing in my betta's quarantine tank. Hopefully somebody can tell me what it is. I have no idea how it got im my tank. I have never had plants, just boiled rocks and well washed play sand. The only thing that i have added to the tank is a new betta. There is also this weird translucent blob on the substrate about the size of a pea. Thank you for any help. I am not sure if i should be worried, either way i find it interesting.
