Like the Tiger Hybrid Endler the Black Bar Endler came from to Redwood Aquatics in Christchurch to me. They were part of the same shipment and once cleared quarantine I managed to source two females and four males. Again, the first goal was to build up stock numbers and secure the strain. After that I started selecting the best males and put them together with three females. Since 2013 they are doing really well and most of the males are nice examples of a Black Bar Endler.
BUT since I didn't purchase the original stock from AdrianHD of SwampRiverAquatics I cannot be sure they are pure Endler! Especially after in the 6th generation's one single female with a extended dorsal fin appeared - but more about her on another page.
My Black Bar Endler are very hardy and breed rapidly. This makes it hard to keep a top quality because they would just inbreed uncontrolled. I usually keep some nice looking females separate and pick the best looking male and put it with these females. After the first couple of drops and before the young males are sexual active I put the females in the next tank. If a better looking male appeared I will swap him for the older male.
