Dwarf lion reef safe?

[beaker020]

The other thing to consider with lionfish in a reef tank is that they are copious waste producers. They eat a lot, all at once and they poop a lot, all at once which can overload your bio-filter. This can cause ammonia/nitrite/nitrate swings algae blooms and inhabitant stress. A overkill protein skimmer will help alleviate this.
