I have two black arowana, about a foot long in a 210 gallon aquarium. I do frequent water changes, and have two very large marineland sumps with a 16w uv sterilizer. No ammonia no nitrates, ph is about 7. They get crickets, cichlid chow, beefheart, the occasion quaruntined feeder, silkworms, mealworms, waxworms, and the occasional pinky. One seems to have a series of small holes running down the top of hes head and along his lateral line. They are very small and the same on both sides of his body. Im not quite sure what this is, and I am having a hard time finding a picture that shows anything like that. They seem to be spreading so im getting worried. ANyone have aany experience with this kind of thing? If you do, mabye you could give me some ideas on how to deal with it?
Any help would be great!
