P.S. any actual brand names of coolers would help..oh and, will they tolerate the slight current from the filter, i havnt ..put them in the main tank yet, waiting for the nitrate cicle to kick in and PH levels to stabalise, sumone said 8 is a good PH level, surely not!? i would have thought 'newt'-ral 7 is best,,, and i lowered the land so that ther is about 1 centimeter of shallow water, but haha he just climbed onto the vertical side of the tank, he seems determined to stay out of water, will this fear of water prevent it breeding, plus
