Newbie looking for a shrimp

Hello AC Members!
I was debating whether I should post this in Newbie but I figured the invertebrate portion takes priority. I have a 29 gallon tank that is running really well thanks to this forum, and am looking to add something other than a fish to it. This is the beginning of my second year in the hobby and have had many loses with roughly 3 original survivers. I did have a African Dwarf frog which was very neat, but he didn't survive the move from my original ten gallon to my thirty gallon. SO, enough of the past. Anyone have any interesting suggestions for a shrimp or frog to add to my tank. I really am interested in visual appeal, but obviously tempermant, hardyness, and "the best fit" take priority over anything else. I do plan on adding one more female guppy and one more female platy, but rather than buying one the two I have are pregnant, and I am just gonna raise a few, snag two females (one of each) and sell/donate the rest to friends/pet stores.

THANKS IN ADVANCE GUYS/LADIES! :headbang2:

This is a month old picture of my tank.
I have the beta in the plastic breeder cage next to the filter, and have added the pleco and beta since this picture. Also, the silver-tipped in the beta tank has been donated to a pet store due to temperment/bullying issues, and I also added three neon tetras since this picture. Also, the Java moss was added to the front/middle left of the drift wood without covering any of the three holes in it. Plus, I spread the Wisterea out so it lines the whole back of the tank instead of just the back of the left half. Just incase any of that info helps people with their suggestions!

Hope this helps msjinkzd,
One Clown Pleco, One Beta, Two Platys' (1 Female, 1 male [soon to be 2 females]), Two Balloon Mollies, Two Neon Dwarf Guarmis (SP), Two Guppies [1 Male, 1 Female [soon to be 2 females]), Six Neon Tetras, and One Indian Glass Fish.

The picture should show how planted except imagine how the Wisteria is lined along the back, and extend it by three more plants. What I did was trimmed a few of the long ones I had in there and the replanted the tops along the back right have. The thing frows like a weed so doing that is not a problem. Also, the Java moss hasn't technically come in yet. It is supposed to come in the mail tomorrow thur monday. So I should have it soon. I guess saying low to medium would have been an easier answer.

Blue,
I am not really interested in having more than one tank. I am a college student living in an apartment, so I have limited budget and only make one year living commitments. Really I am looking for visually appealing hardy fish that can make the moves from one place to the next. I use the 10 gallon as a temperary home for my fish while the 30 gallon cycles at my new place. At least that is what I have been doing. I do have a 2 1/2 gallon tank that I use for a hospital tank, and am going to use for my baby guppies and platys.

Okay, the verdict seems to be that shrimp would be a bad idea. What about African Dwarf Frogs, or any other completely underwater frog? Does anyone think that would be a good idea? Perhaps I should just be content with what I have.

I did forget to mention however that I have a Mystery Snail in there also. I got him to test the levels before I had test kits. I doubt that would change anyone's mind but just incase thought I should include him.
