Small Tank

[Goalie Kid]

Hey guys im currently having problems deciding what to put into my 20 gallon long tank. I was wondering if there was anything agressive like an eel or lionfish or anything i coould keep in this tank and if there is how much rock do i want in the tank? I currently have 7 pounds in the main tank and alot more sand floor space left.

Any comments or thoughts in anyway are very appreciated.

Also any suggestions at all agressive or none agressive fish would be greatly appreciated.

Thanks again
Zack

I would go with either a frog fish or octo.

Dwarf octos have a very short life expectancy, are hard to obtain, and even more of escape artists than regular octos because of their size. I'd go with a frogfish, they are equally cool.
