That size of the creature was definitely something I was looking at. And you helped me with that. Like I said I’m keeping it simple. And don’t want to cram a bunch of stuff in my tank. Small works for me. And if I add nothing else other then my hermit crabs then that’s fine by me. The light and anemone was all a fact finding mission. Plus side. I did find a Fluval sea marine nano on eBay new in box for $30. So that’ll increase my options. But still. I’m not going to hook it up till I decide on something else. No need to break it out yet.A tube anemone would be good because they don’t really care about light but as a prior owner…they get huge, the tube under ground gets huge, and it will outgrow a 5g tank
