Ok I have a 20 gallon long tank and right now theres one false perc Clownfish in there. I'm using a stealth heater,and an aquaclear HOB filter.but I am looking for an all in one sump (30gallon) for my tank right now and plan to have one next week. Anyway im planning on adding 3 more false perc clowns, and I really want an anemone but i've been researching them and they seem really hard to keep alive for more then 8 months...at least some of them. Anyway i was looking at some fake ones and they look really real and I was wondering if the clowns would acclimate to a fake one? Also with the perc clowns which is the anemone to get and also easiest to take care of. And what other fish could I have in my 20 besides the 4 clowns? With and without the live anemone, I would hate for a $40 Goby or something to get eaten by the anemone...as i've read is very possible. Thanks for the help in advance.
