I change 50% of the water every Sunday without fail. Sometimes, depending on water conditions, I may change 25% once during the week. My water remains crystal clear and there isn't any 'fishy' smell. In fact, I put some Rosy's in there about a month ago for food and somehow, one of them survived and has grown too big to be eaten! I beginning to think these aren't Green Terrors at all. As for being stunted when I bought them, they were VERY small so I think it's that.
Blue acaras sometimes are mistaken for green terrors, and they get to be aobut 8" total, but they do grow very slowly, i have had many as you will see in my signature, i have had them for about 2 years now and the biggest ones are about 4-5".
