If you ever have any questions about your fish aquarium feel free to message me. My dad owned an Aquarium business for 16 years so a lot of his knowledge rubbed off on me as I was growing up It's quite pleasant to have a fish tank.
Oh, thank you! The crayfish shed his skin recently. My heart turned over when I saw that skin, thinking he had died. But, then I saw his little claws on the edge of the hidey place we put in for him, so I knew it was just a skin. He is very active, and I've seen him lurking in the greenery, as though he wants to grab the fish, but I think they are too large for him.
