puttin too much rock in the tank is probably the best possible thing you could have DONE!
i have 28lbs in my 18 gallon.
rock + flow = good reef mojo.
now, being that were have a 6 gallon dif. between our tanks, id suggest buying SMALLER colonies or FRAGS, i did this to maximize diversity.
if you just want a handfull of a few specific corals, then yea, buy bigger colonies.
as far as these things go, they're cool. if you dont want them stealing prime real-estate, just isolate them. keep the colony on the sand bed, away from your rock work.
but being that they are a living oranism, id bet you ten bucks you bond with it, and become attached
i know i do. (id name the pods if i could)
