Hey I hear you about the long fin Matt it can be a pita. Ive noticed some improvements in scales and tail quality in the f2. Lots of variation still and some unique looking fish. In the next few days Im going to start numbering their pics to keep track. Took 10 babys to the store today and just got a call that they sold already with good comments from the customers so made me happy. Ive got so much fish work to do its ridiculous not that Im complaining (maybe I am) but it is so hot that my energy is near zero.
