Aquarium Advice FINatic
I have been on a hunt for these fish for almost a year, and finally found some. Now that I have them, a few questions come to mind:
1. Are these a completely different species from either the German Blue or the Bolivian, or are they merely a color variation of either of the above?
2. How do you sex them? The ones I got were fairly young juveniles, so it may be too tough to tell anyway. But the ones I suspect are females have a much lighter coloration, and do not seem to have as much of a pronounced dorsal spike. But those are the only discernable differences. The difference in spike is somewhat negligible, so perhaps it means nothing. And as far as the coloration, could the difference just be due to dominance? I know that with some fish (e.g. clown loaches), the fish that establishes itself as the dominant fish can sometimes tend to have a darker color, whereas the other fish will lighten somewhat. I don't know if that is the case here.
3. What else can anyone tell me about these marvelous little fish?
