My first question is in reference to diet. I have a spectacled caiman who has a diet which mainly consits of rats and fish. I fed him a boneless, skinless chicken breast that I picked up at the grocery store. I know nutrients are lost when feeding frozen food such as this, but felt it may be beneficial to add a variety to his diet (also if he eats 1 part chicken to 2 parts rats, it would also cut some spending). Is raw chicken okay for my caiman? Also is this a good suppliment, I would appreciate any recomendations.
My second question pertains to his enclosure. Presently he is just under 4 feet in length and for the time being has a suitable enclosure (6 foot water area/14 foot enclosure). I am expanding the water area and have drawn up a few plans. Has anyone used pond liners? I am afraid he would tear the rubber liner and was wondering if anyone has experienced this, and secondly if there are any suggestions as to substrait I could use to prevent this. I have a couple of ideas, but would appreciate any suggestions.
