Is this overcrowded? i think so...but not sure

[drater]

OK so i have a 20 long, soon (as in by this weekend) to be a 30 gallon tank, in which i have
1 perc clown juvenile
1 banded goby
1 bangaii cardinal juvenile
1 pajama cardinal
1 flame scallop
a dozen or so blue leg hermits
3 astrea snails
1 small black brittle star
1 firefish (whats the actual name for these guys?)
and 3 juvenile damsels

..writing this out it does seem overcrowded, but not to fear! water quality is still fantastic, 0 ammonia, 0 nitrite, i have an emperor 280, and a filstar xp2 running constantly

i am planning on trading/selling off the star, pajama cardinal, and perhaps a damsel or three, any ideas? or should i shoot myself now

I would lose the damsels and a goby/cardinal....a few too many.

Get it down to the three or four fish you like most. When they start to grow a bit, that is just too much, unless you want a really,really high maintenance life.
