I am too afraid of Lion fish myself.. I had one when I had predator tanks and between the wolf eel and stars and stripes puffer that was in the tank with the Lion, the lion never got any food and starved to death. I was much to afraid to stick my hand in the tank to feed it knowing that one small touch would send me to the hospital, and feeding sticks didn't work because the other 2 inhabitants would get the food before I could even get it close to the lion.. even if it were a lion only tank... those are just too dangerous of fish for my taste. I can deal with predators, just not super poisonous predators like lions. Like I said, I did an aggressive tank for many years.. not really looking to do another, I want to do something I haven't done before.
Bala sharks.. I don't even consider them a shark even though the name says otherwise. Any real shark like a tiger shark requires a much bigger tank, and I am not the type of person that believes sharks belong in a home aquarium unless your a millionaire and have someone on staff that just takes care of the 10,000G+ tank.
Thanks everyone for your input though.. I do appreciate all the posts even if it isn't the direction I want to go. I am just brainstorming and any extra brains in the process helps.
So, my options are:
FW Planted
Terrarium / Turtles? Lizards? etc. (can you do a SW terrarium?)
Seahorse
Octopus (not high on my list)
... can't think of anything else at the moment.
