Hi guys I just wanted to share my two clown knife fish that's in my 450 with my stingrays. There about 12 and 14 inches. And extreamly tollerant with each other and the rays. The smaller of the 2 knife's is starting to darken down showing alot more purple color then the larger one. I'm thinking maybe a male and female. Here is a pic. I'll try to get a few more of them today and post them up also.
