I have a 250 liters tank and have had one 5cm bristlenose there for some 3 years now. Yesterday I introduced a 15cm L200. I had no idea that the smaller bristlenose would get aggressive and start chasing the bigger newcomer. The bristlenose for instance got stuck on the L200's mouth area from it's bristles. I had to take the smaller out of the tank. Is this behaviour common? What should I do?
Then another question: do Zebra pl*cos get well along with L200? I would like to get one or two zebras.
Thank you! Do you think there is any chance the bristlenose would ever get along with the L200 or do I have to get rid of the other one? Do you think that if I kept the bristle away for a week or so n put it back into the tank it would behave better?
