Just finished my budget caiman paddock for my 30" P. trigonatus. Composed of a 6'x4'x2' Laguna pond, a smaller 4'x'2.5'x1' Laguna pond and an old reptile/bird cage. A few bits of wood and assembled with my shoddy carpentry and voila!... I'll try to get pics of the caiman when he stops hiding under the bark
