well i lost the molly but i have a smokey/marble angel and a bristle nose pleco in its place. i only have 15-20 gal tank so im pretty much maxed out. but on a better note the tetra and tiger trade nips and chases. they seem to be fine and all are growing remarkably the tetra being the slowest as he was big when i got him/her (name is shelly). and dispite a few warnings on this site the angel and tiger compleatly ignore each other. relief! all is well and my fish all coexist with each other.
