I was thinking about plans for my 20 gallon jbj cubey and I was thinking about adding in a bubble tip anemone. Would I be able to keep multiple kinds of bubble tips in the same tank? And would a 20 gallon be to small for anemones and other corals, considering they will all grow significantly over time. If I was going to keep anemones I would get 2 clownfish to hopefully host them. Thanks!
