I thought you would of keep at least a pair......the Costa Rican male I have is looking pretty good...fins are a bright blue along with some on his face. I am pretty happy the way he is turning out....he might be 7" eye ball. The female is growing extremely slow. I just got some Nicaraguan from Jeff Rapps a few weeks ago.....they are beating one each other already. I have them growing out to get a male. Good looking new stock keep us posted with updates. I have thought about many of the fish you have posted....all nice choices
