Hi all, I have had a GALS called Turbo for about 14 months now. He came to me with a healthy shiny shell, very active, eating well and reguarly laying eggs. I have noticed over the past year that his condition had deteriorated since I got him, particularly in relation to his shell. I first noticed that the area of shell around the opening had started to become ridged and uneven, and this effect began to spread up the shell. He now has a good inch of shell around the opening which is uneven and ridged, and it seems to be continuing to spread. In addition to this, his activity levels have slowed a bit and he doesn't eat as ravenously as he used to. He has also hardly laid any eggs since being in my care, wheras before he apparently used to lay hundeds at a time. I always make sure he has cuttlefish, and I try to give him a varied diet of green leaves, red pepper, sweet potato and fruit. I was feeding him spinach until I read this contains oxalates which can inhibit the uptake of calcium. I am concerned the tank may be too cold and dry, I'm not sure if this can affect the condition of the shell? I have recently acquired a spray bottle and have been spraying the tank daily to try to keep the humidity up, but my room in this shared house is quite cold at the moment so it's difficult to keep the humidity up. I have a heat mat under the tank, a shallow water dish and a cloth over the lid to keep the moisture in. Does anyone know what might be happening to his shell? I'm concerned that if I don't identify the issue soon he will continue to deteriorate. Many thanks!
