New pico/nano. Also, Assuming hydroids..

Just searching the forums these look like ones I shouldn't be too concerned.
Yay?nay?
Anyway tanks a little 2.5gal with a high-tech ac20 decked out with prefilter, filter floss and chaeto. It's over a month cycled, just kinda slow rolling it if I need to wait out these guys b4 adding coral. Enjoying watching it go through the stages. To think a week and a half ago it was cover in hair algae

Rock scape looks nice, the hydroids should go away as your tank establishes. In my experience they didn't harm anything :). What do you plan on stocking this tank with?

Fish wise I'm pretty limited, possibly one of these minus the court jester. I feel they need a larger established tank.

Corals, looking at encrusting montis up top and LPS/softies around the base. I'd like to do a mini maxi nem for the sexy's I just don't want it going on a walkabout through the tank. Maybe toss that in first and let it settle in. Tank measurements are 18x6x6"
