clap clap good choice. I have biocube 29, but my lfs in my area told me they wont survive with 36 watt compact lighting and say i atleast need T5 lighting for them to survive. So Im not sure anem is good idea for biocube unless you upgrade your lighting to T5 or MH. If you still want your clown to host on something, and kinda has anem's feeling, you can try torch coral.
