Today I noticed my blue zebra faded to almost white and has a big brownish sopt along the fin.
Its in a 55g tank with a red zebra. And giraffe hap. The blue zebra is the only one that has this anyone know what it is
All the water test come back safe. Tank is at 80 degrees. Tank has been setup for 3 months. Fish is eating fine and swimming around normal. Filter is a pinguin 330 . Tank has slight green water... overnight the mark got bigger and one devoloped on its head between the eyes and now there is a few black spots on the fin on top. The. Fish is about 4-5" and is a few years old. My other red zebra and giraffe hap are still fine so far
Continue treating with melafix as per instructions. If the condition worsens or affected areas on the fish become fuzzy you should begin treating with an antibiotic such as Maracyn and Maracyn 2 (used together) or API Furan-2 after performing a 50% water change.
