Yes, I understand with what you say Baccus. I caught a 10th of new ones today, including some black tiger looking like. That's a thing I was wondering about: are all the different colors I find are just offspring's, or are they trully different?
Here are some pics of the new critters. Sorry for the poor quality, I really need to buy a better camera, rather than the one from my phone.
They are "reddish" for the moment, they will be black & white in 2 more days, after they settled in their new home and calm down.
This one has more white than the others
