Have had a sebae for almost half a year and a RBTA for about a month, both are great showpieces and though they required much planning ahead (and they don't like your plans!), definitely worth the time and trouble. Both are dinner plate sized and have hosted clowns (fallow atm), and will do so after fish are back in. Amazing creatures.
RBTA did manage to wreck some nice xenias which my wife wasn't happy about.
