Anemone for a biocube

[fooser]

I think this can be done. I kept a RBTA in my stock 14gallon bio cube for about 1.5 years and it was very healthy with bubbly tips and bright pink color. The reason I had to take it out is because it eventually got so big that it took up almost half the tank and stung other things (the person who took that anemone off me could vouch for the size). If you stick with a smaller one you could probably do it though. but who knows, maybe that was a freak incident with a very hardy anemone. Either way, good luck!
