Crayfish trying to walk through glass in corner of tank.

    Hi all,

    My cray female is spending most her time in the corner against the glass just walking forward and forward and foward getting nowhere. It started Monday morning.

    Last week ive done more water changes than regulary cause i brought a fish from my tank at home that had been attacked. Dont know if that could have an effect on this behaviour?

    She moulted about 4 weeks ago, perfect moult and ive added 5 ml iodine just to get back the nutrients she needs after moulting.

    Please, any advice???

    Could the fish be a predator and the cray is feeling threatened?

    She's been in the tank for a while now, right? I don't imagine it's a TDS issue or it would have been an issue before now. What kind of fish was added?

    She's in the tank now for almost a year...
    Its a sword tail fish. Not aggresive at all towards any other fish.
    The sword tail lost his tail aswell about 6/7 months ago by a other cray, so i cant imagine that he could be a threat to this cray.

    The sword tail ive added monday a week ago, this started this weeks monday a week later...
