virgil2090 is giving you good advice. I would second the large SDs as a dither although I know what you mean about not too exciting. There are different types available. I would give whatever you put into the 125 besides the dithers awhile to get established and larger before you add the jag. That way it's lower on the totem pole from the get-go. Gives you a better chance of things working out. Don't have experience with FH's, but the JD didn't work out for me. Not tough enough although I will say I had 2 m/2 f in the tank at the time along with some oscars and SDs.
