I have two angelfish in my 36 gallon bowfront along with 6 sterbais and 1 BN pleco. All of the fish are small and nowhere near being fully grown. The Angels are only 2 in. high still. With this mix, can I add 12 Blue Emperor Tetras so they grow up with the Angels and will be considered family, or will the Angels eat them someday? Just so you know, I'm overstocking a little because I am over filtering quite a bit too.
