For a cuttlefish, the koralia are probably fine without modifying it. The intake is very dispersed unlike typical powerheads. I run vortechs without any modified covering and they are much much stronger then koralia pumps. Once in a while I would see a cuttle against a vortech. I would walk closer to the tank to turn the pump off, thinking that it was stuck, but the second it see me, the cuttlefish leaves the pump on its own. Ive later learned that they sometimes like to do this or play in the flow. However, if the cuttlefish is weak and dying, just like any animal, it may get stuck in the pump. This situation often causes the incorrect conclusion that the pump was the cause of the cuttles demise, not realizing that the cuttlefish was dead or dying prior to it getting stuck in the pump.
