New tank what to do? FOWLR?

I just got a new 120g aquarium that all my stuff from my 90g went into and was wondering what to do with the other tank? I have been thinking species tank and if so what species do I want? I have also been thinking for a aggressive/not reef safe fish but do not know what to stock it with. Please give me ideas for stocking it and what kind of tank it should be. Sorry Octopus is out I have decided for how much they cost to only live more then a maximum of 2 years is not worth it.

 

Do a pred tank! Lion fish groupers angler stuff like that maybe a large eel!!! i just bought a baby panther grouper......sickest fish i have ever owned!

 

That is what I was thinking about doing but I am not sure what I can put in there. I would like a porcupine puffer a Black and White Heniochus maybe a Black Lionfish maybe a Banded Moray eel. I am just not sure about what can be mixxed in a pred tank.

 

Pretty much make sure nothing can fit into the others mouth!

 

Yeah I got that part down lol! But I do not know what all kinds of fish I should get so I am kind of stuck. What do you think of what I have mentioned so far?

 

I like it!

Heres what my 125 long pred tank is gonna look like

Dragon eel
Lionfish
sting ray
panther grouper
some type of angler

 

Sting ray Hmmm Dont you need a lot of open sand to keep those well?

 

Yup dont plan on having alot of rock in this tank, maybe a couple pieces but thats about it

 

What different types of species do you think I should look into for a species tank?

 

Stingrays should have at least a 3' wide tank with a HUGE footprint, or a lagoon like pool converted to saltwater. I have seen videos of anglers eating lion fish of the same size, and a panther grouper will out grow a 125.

The lionfish and dragon eel (I hope your talking about a brazilian and not a hawaiian) would be fine in a 6' 125 along with something like a harlequin tusk and maybe a miniatus grouper. for the 90 pred tank I would go with a smaller eel, a dwarf lion or 2, and maybe a dwarf angel, or a smaller species of the larger angels that dont get over 10". or a smaller tang like a scopas or kole.
