Hitch hiker ID help

[d.grcich]

I have never kept blasto's, micro's or any other such corals so I do not know what these are or what is the difference between them. If someone could shoot me in the right direction so I can read up on them. Thanks alot,
Dave

looks like favait or echno sry about spelling lol both usaly very hardy.Sweet zoo's by the way also

looks like montastrea sp.-should do well especially if you feed it-chip them off that rock though and attach them to some rubble cause they will get out competed by the palys

Looks like acan echinata in the first pic. I've had a few of those brown with tan stripe morphs. Not sure on the second. Most likely a favia of some kind.
