Hello; I answered on the basis of all tanks. For example I have a pair of angel fish in one tank and numerous of their offspring in two other growout tanks. They all count as one species.
I also took each distinct species to count. So three species of tetras count as three and not as one of tetras. Not sure how the various hybrids may count. In general if they can interbreed they are of the same species. To me that will make zebra dainos, spotted danios, and perhaps pearl danios all of one species for it is my understanding they will interbreed.
