Both my Bettas have spots on them. Black specs on their bodies. I was wondering if this was due to the fact that they are probably mutts? Or are they I'll? When I first got narcissus he had these spots already. Charlemagne has some but definitely not as many as narcissus. They are both very active and look very happy. No itching, or ramming into stuff. Is it something that will progress and be harmful or is it normal for them? Also, I want to grow my own brine shrimp culture so I can feed it to them. Is there anything I should watch out for when doing this? How do I feed it to them? How many and how often? Can I mix pellet food and brine shrimp in their diet?
