Agree with Shenz, I have 7 Red Sevs which are all between 3-5 inches. They were all red when I got them around 2" from my Local Pet Store. They were hard to come by here in Indiana. It took my local Store over 3 months to get them but it was worth the wait, they are beautiful fish. I have some Golds and a few Rotkeils and everyone is starting to pair up now in my 125. Just moved a Red Male and a Gold Female to a 30 gal and they laid eggs Tues PM. I have also read that the Red Males are infertile. I am hoping that's not the case and will let you know how this batch turns out...This pair did lay eggs in the 125 but everyone else ate them..
