LOL whats panties got to do with fish, for real though if you don't want the opinions of others do not ask the questions, don't come off half cocked when you get those opinions, take it for what it is worth, but yeah i did keep 3 2" Front's in a 55gal when i was a lot younger and just getting into Tang's that was well over 15 yrs ago and i had typical Mbuna in the tank with them, the Mbuna tore into the Front's killing two of them and i had to euthanize the third because they tore into his tail fin and into the flesh where it would not have regenerated and the fish was suffering, then later down the hobby path i had 5 Front's in a 120gal 5' footprint mixed with other Tang's, I had them for 5 yrs eventually selling them to someone else who had a larger setup..
You are right in the sense they do grow slow as with most Tang's and if you acquire small Juveniles they should be fine in a 40 breeder for a little while but i would not add Mbuna in that 40 because the Mbuna will grow faster and will cause problems, if down the road you obtain a 125gal and your Fronts are of size like 9" I would say a group of Yellow Labs would be fine if that's your cup of tea..
Have fun and enjoy the hobby..
