Will be attempting any captive breeding? It would be interesting to
comparing both species for suitability as commercially viable, ornamental
species. I shudder to think of what might happen if these fish were
accidentally introduced into the Japanese irrigation canal, river and stream
systems (if they are as environmentally adaptive as you say) but they would
be well received in the petshops.
