Hi Gary My male Alenquer is around 2 1/2 inches long. My females are quite small, around 1 inch long. I do have them in separate tanks for the moment.( Big male and small females) Can`t catch the male yet, in the heavy planted 35 gallon community tank. Don`t want to mess up the tank, but I think I will have to, to catch him Should I wait till the females grow a bit, before I put them in the same tank? They will be going in a 20 gallon tank. Where did you get your Alenquer from?? Thanks George P.S. It was nice talking to you again at the Montreal Aquarium Society
