I had 4 Talbot's, and now down to 2. One of them was most likely killed by the 2 biggest ones, and the other one I just lost this weekend --- was redoing the tank, and a rock fall on it.
At first they were pretty mellow, but as the months have gone by, they have gotten more aggressive -- towards each other and other fish in the tank. I still like them, but don't think I would get them again.
