Thanks Duanes for the info......8 inches for a male in a year I can live with.. I started with one bought 2 more and the 3 total was in short time reduced to 2.... would have liked to had a pair but the one that appeared female was killed off, I believe it was a combo of sickness with the aggression.... at this time it looks like I have 2 males ... currently I am doing about a 75% water change once a week in a 75 gallon,....... thanks for showing the pics of yours they look great(I hope more people chime in and post theirs)....a pic like the last one of yours is what created a want of this species for me....
