I got 3 baby BNs a month ago. They are still smaller than my corys but the biggest one is a pain! He chases everybody, corys, shrimp, rasboras, snails, he doesn't care. If it moves he is going to chase it. Will he always be like this? Should I start looking for a home for him before he gets worse? These are my first Plecos so I don't know if this is normal behavior or not. Any advice?
