What to put in a 20

lol, I'm not certain on this one... The angler and frogfish are both considered to be at easy-moderate care level.

Anglers & Frogfish

 

ill deffiently have to do some reading up on these guys, they all seem like neat fish

 

leaf fish are also cool. they are a cousin of the lionfish, are venemous, and are ambush predators. they sit and wait while swaying there bodies like leaves. they are 50 bucks around me but are definately cool. just another idea out of my favorite fish file

 

Ah they do look quite a bit like anglers too! At least the red/orange angler.

Bat fish look pretty crazy, but require about 200g

 

Too bad your tank's not bigger. lol

Tassle Filefish

 

how about a maroon clown fish? they look pretty cool.. Very colorful red ( maybe a pair)

frogfish is a good idea too. ( although i would like to see a fish that moves a bit more but JMO)

maybe a Lion fish.. they look amazing!.

or a goby dominated tank? like 3-4 small gobies.

 

Arc-eye Hawkfish
long nosed hawkfish

maybe a pair/small school of pyjama cardinal fish or banggai

CUTTLE FISH!!!! TANK.......

A box fish are pretty cool too!

maybe seahorse tank ( if you are up for the challenge)

 

While seahorses are really neat, I do believe they require an 80g tank. The same goes for cuttle fish, But I'm not certain on cuttles.

Box fish are awesome. Once again, too large.

really?? ive always seen boxfish at the LFs the size of a quarter.. thats why i thought they were naturally small lol.....

then again.. most fish start out that way too lol

 

lol. The fish you see at the LFS are, in most cases, very young, unless in the FS DT's.

I think these box fish grow slowly, but do become of decent size, topping out at 1.5 feet.
