Ive been reading a lot about how these guys are slow growers however this little guy put on about and inch in 3 weeks. He was about 1.75" when I bought it three weeks ago and is now 2.75". I was wondering if this rate is due to it being so young and the rate will slow as it ages? Also my old lady likes to name my fish and I was wondering how old/big they need to be determine sex? Sorry about the bad photo but the little scamp is quicker than my camera.
