Hi All, Does anyone know at what age/size D.maculatus begin to show the difference between males and females. My friend spawned them in August and they are now approx 0.75"TL. All 18 still look like females with clear tails. They were spawned in de-ionised water with pH~5. Thanks, Ken. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
