I had 1 pictus (~3"), 1 peppered cory and one recovering dwarf puffer in my "QT" tank. Pictus and a cory underwent ick treatment and it was already 2 weeks as they settled down nicely (another small cory died from the ick). DP is living there for a week and a half and still a little bit down from his injuries (i.e. - abs harmless).
Pictus is very neurotic fish but never looked like an agressive fish to me. 2 days ago I sarted noticing that my cory is kind of unhappy and his fins a little bit frayed. Considering the quiet life they are supposed to lead there i could not understand the reason. Today i saw it! The pictus chased the cory and tried to chew on him! The pictus actually is very well fed, so it should not be hunger. I had to remove poor cory and put it into my 29g tank. Have to see how he'll be there. There is pretty tight life there in this 29g.
