i just got a 20 gallon tank setup for free from the in-laws!!! nothing special just stock lighting and powerhead filtration. but it was for FREE!!! i really want to get a false perc. is it okay for me to put 1 in the tank.(how about 2?) I plan to get at least a 55 gallon bowfront in the middle of next year. so he would only be in this tank for maybe a year if not less. will i need a protein skimmer. i know smaller tanks get dirtier faster but how hard would it be to keep it clean with a 20 gallon. i have two seperate powerheads if that makes a difference. also what would be the best anemone to put in it. this will be the only fish (or two?), plus the anemone?, and some cleaners(any recommendations?).....and since this tank is mine now...when i upgrade to the 55 gallon, the 20 will be the sump. thanks for all the help guys. oh and one last thing...oklahomans and texans....what is a good marine fish store to get a "nemo". i just hate knowing that i would be paying at least $23-$30 on shipping alone plus the fish. are their any good LFS in the OK,TX area.
