I'm having problems with my male dovii I just got about 2 weeks his about 6-7" and not really eating and is always hiding in back of tank he has a light color to him he has the black stripe on it's side his fins has nice color but doesn't have the same color as other dovii I've seen that's about same size Or smaller. He shareS tank with female jaguar that's a healthy 8". Is this normal since his new to tank? Last but no lease I'm curing ich and it's been a week already spots is gone but I will continue for one more week. Don't see spots no more but still brushing up against the gravel.
