[black molly3]

i bought some live rock well coral rock today with some beautiful mushrooms on. the man also gave me a cluster of button polyps aswel as i am a regula. now one thing to id s the polyps. have they got a name some of them have an orrange spot in the midle and some have a greenisg spot in the middle. here is the best pi i could get.
do i have to spo feed them with brine or will they do the work

the rock woth coral on also had some polyps on

now the thing i am eager to find out is, is this a hamer corral. it is tiny at the moment and is barely 1 cm yet.
not a very good pic

and here is the tank as a whole.
the glass is a bit dirty haha

i dont think it is a hammer coral because it has started opening up in all different directions and do you know like polyps have little tentagle things. each individual had the same but the tentacles are black they havent opened uot yet fully so we will see what happens
