I have a communitarian aquarium, included a group of 6 rummy nose tetras (Hemigrammus Rhodostomus) From one day to another a white ball appeared in one of them, just that it doesn’t look like anything I’ve been searching in internet buying medicine online to know what medication it needs. Please check out the pictures and if you can help me I will truly appreciate it.
