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???
