Lutdfie,
i had a flakey when i did not hv any coral last time. it iz relatively easy 2 keep. thou it doez not bite or eat coralz it will push coralz / rockz az it movez so make sure ur rock settin' iz firm.
i kept it 2gather wif triggerz / lion fishez az they feed on similiar food (live food the best - those fresh water shop sellin' packeted catfish).
thou thiz may sound cruel but it'z pretty interestin' when the triggerz / lionz / eelz hunt & give chase 2 their feed. yez... strictly no shrimpz & invertz
CAUTION when keepin' eel, COVER UR TANK TOP az they can crawl out of the tank wif the help of ur high rock structure & glazz hangin' equipmentz. oso wat u can do iz 2 get those PVC pipez & just leave them on the sandbed. in any case if they do make it their home, it will b much easier 4 u 2 catch it when u wanna get it out of the tank.
