Large mantis shrimp will feed on your inverts and small fish.
Aiptasia can sting your corals.
Bristle worms are normally beneficial scavengers, but when they get big they may start to feed on perfectly healthy tankmates.
Fiji LR is lighter and generally more porous than other types, which is why I prefer that. 1-2 lbs per gallon is recommended.
