He has Black Spot disease. His head and body are covered in small black spots. I've been so involved caring for Phlox these past few days I haven't been able to pay close attention to the others. If anyone has any information or experience with this parasite please let me know. From what I've read it's not fatal but it could cause secondary infections. I am buying some Tank Buddies Parasite Clear right now. It claims to get rid of black spot. As soon as I can I am getting some new gravel, tearing apart his tank and throwing out his gravel where the parasites are. Apparently they can live for months in the gravel even without a host. Lava seems listless and depressed. I hope he hasn't already gotten a bacterial infection. He's acting a lot like Phlox did at first. Hopefully I can cure him since he's not as advanced. Maybe that's what ultimately killed Phlox but I couldn't see the black spots on him because he had a dark body. Lava is pink on his body and it's very obvious. I just can't deal with losing more fish. Maybe I should treat them ALL for parasites.
