Advice? Non reef safe fish in a reef.

I had a puffer fish in my reef tank. Not a problem until a powder brown got the food first... Puffer didn't miss his meal.
Took the lips and teeth off the tang and died once scar tissue overgrew. Feeding frenzy gone bad

 

I had a baby tusk once...loved it... but didn't stay very long as my mystery wrasse wain't having it! The only real issue I see in those three (besides inverts on all of them) is the lion. A lion can be done...but keep in mind how often your hands/arms need to be in a reef tank compared to a fish only...and keep in mind he will be in there too. A lot of people have issues with them in reefs because once adjusted to captivity they aren't really afraid and will come around when your hands are in the tank and there lies the potential for getting stung.

 

I had a 6 inch Aussie Tusk and was great except with smaller wrasses. I had to rehome him. Never touched a coral or my Fire shrimp.

 

Had a couple of lions in a reef (one got to about 15") and never had an issue. They are pretty slow moving so never had an issue with my arm in the tank. Now, the Niger trigger was another story as he always made a rush at my hand when it was in the tank.

 

So you have seen my tank and I have some non reef safe wrasses, an angel, and a marine betta havent had a problem

 

The dendro are out and I think there was pellets near it cause I did feed the tank while you were there also
