Someday they will be big, at least for me! Everyone has grown at least an inch since I got them, except for the silver dollars and loaches (which I have gotten after the fact, but they have gotten bigger in the last couple of weeks). I think the Nicaraganese is a male. Still not sure on the Polleni or Robertsoni (If you know could you let me know). The Convict is female. I am pretty sure my Severums are both male (the gold doesn't have the typical squiggles, but the female convict was trying to get him to spawn with her). The biggest fish is my Rhino Pleco at about 9". The largest regular fish is my Gold Severum at about 5 1/2". Hope you enjoy.
