Check this http://www.aqua-fish.net/show.php?what=fish&cur_lang=2&id=305. There you’ll find a post marked as On: April 11, 2007, 5:06 am. BTW, you didn’t mention how old is your bristlenose. Old specimens are not resistant against various diseases as much as juveniles are. If he/she is about 4+ years old, it’s normal that they get sick. Additionally, bristlenoses can get sick if they eat other dead fish. For example, if there was a dead tetra or other fish in the tank, then your catfish could get infected from it. It’s very common way how they become ill. If you have more details, feel free to ask me. I keep this species since I bought my first tank, so that I have enough experiences. jan 2008-05-03
