Quite the possibility with the eb acara. Considering it doesn't appear to get as large as the traditional blue acara. Line bred until they produce all blue when breeding two EB together.
I am just surprised since keeping Green terror, Texas, jacks, convicts etc was the norm. It has taken so long until now to produce this hybrid. Central hybrids and African Lake cichlids quite common, more so than their Southern cousins. But seeing more and more odd pairings in the cichlid world these days makes you think. I think of lake Victorian cichlids and there will to survive and evolve. Alot of natural hybrids and new 'species' perhaps forced due to predation.
