Whiptails to I.D please

[ridout]

Fish 1 are the first two pics (Hemiloricaria lanceolata i think??)
Fish 2 are the two after ( have not got a clue. Help please)

Fish 1 looks like an LG6. I haven't got time to check for you atm but have definitely seen fish 2 before. I'm sure someone will identify it for you but if they don't i will track it down.

3+4 look like red lizard whiptails... but im not certain by any means...
sometimes these only colour up when they are about to spawn....
