What can I give to my alien fish ?

I'm just starting this one. I know there's a lot more I could do but just don't know what to affix. Anything helps. Thanks. Oh and here's a picture. http://s44.photobucket.com/albums/f37/V1...
some crabs like the flat crabs from the store and other things like anemone and clown fish / blenny / goatfish and other fish some cleaner shrimp are nice
Theres this white item on my goldfish's...
Well if it is brackish water you can put some cheap tomato clown fish but if your willing to spend money you could buy a few trigger fish or some Gobys. If it is a fresh wet tank you could add my favorite fish witch is some jack dempseys, green terrors, afican chiclids, or mabey whether you dont like those fish you could get some gars, knife fish, or some rainbow sharks.
(the dempseys, terror, and africans are cheap)
How do i thieve fish out of...
Answers:    Some live plant, more decoration.

Shrimp are cool.

Maybe some floating plant.

Is it ok to hold on to fish contained by 1 of those plastic bins?   Should i carry an oscar or a lizard?   What classifycation is a stingray contained by?   How within the world does my guppy hold on to have babies even though the males and females are surrounded by separate tank??
