ya, bucktooth tetras would, but they're kinda lame like most tetras. I'd get convict cichlids, they are much more interesting and are alot smarter.

no way! exodons are cool, you need like 15 of them to get any action though then they will be like mini piranhas, he cant fit that many into his tank though.
 
feeding guppys as a staple diet is not advised
1)nutrition
2)disease

feeders should be used as a treat after being breed your self or treated properly.

why not try some aggro mbuna like dogtooths etc they would smash the guppy but would only eat whats small enought for their mouths

try breeding them then feeding the fry to the fish;)
 
what if its all they would eat? my belesox only eats live fish, some people got them to take filets though. i feed them guppies and minnows always gutloaded with lots of different stuff. got a whole pond setup just to feed these 2, 4 inch fish.
 
blitzen- Depending on how they are raised and the species of the particular fish, it often happens that it is necessary to feed them live food as a staple diet. You could always try to accomodate them to different foods, but is isnt always successful. I wouldnt worry about it at all, especially if you are overseeing the breeding yourself. The one assertion that I have always detested is that "live foods are bad for fish." There is always risk involved in feeding live food like guppies, I do not deny that. But that risk is easily minimized, and you can work the nutrition and vitamin element either into the bred fish themselves or by attempting to supply pellets. I certainly wouldnt advocate going out to a chain pet store and buying feeder fish, and I believe that places such as walmart, petsmart, etc..(as well as irresponsible pirvately-owned stores) have done an incredible diservice to the percieved safety of live foods. While your strategy of home bredding is probably the best, it is also good to find a store that you can trust, if possible. Even while I breed my own feeders, I have continued to purchase them from my local dealer, and in my 10 years of experience with him I have yet to encounter a health problem. It is likely the case that many people fail to acknowledge the importance of feeder quality, and it is also difficult to detect infirmities in many cases. But, overall, I would argue that live foods are an excellent option when treated with the appropriate discretion. I think you will be fine.
 
Thank you DWF73, that needed to be said
I am careful and have always had good luck. I have never owned a fish that lived entirely on feeders, but there are some out there. Everytime I have posted a question about feeders or made reference to the fact that I plan to raise guppies for feeders someone jumps in and tells me I shouldn't do it. Proper diet is necessary, but for some species proper diet consists of live food solely or primarily. It is important to know proper diet, and feed each fish accordingly.

Back to the original question: If I had a 29g full of guppies and wanted to slow them down or get rid of them, I would buy a pictus cat Providing:
#1. There aren't a lot of other fish in the tank Pictus get 6-8 inches
#2. You supplement the feeding with a good flake or pellet.

Pictus cats are fun to watch, they tend to slowly work there way through feeders, they are almost always listed as carnivourous, but I have found that they pretty much eat any prepared food regardless of make-up, and they will hunt in the daytime when they are comfortable. Just my 2 cents worth.
 
lots of sites ive been on said i could only feed my saratoga(when i had it) live feeders but i got him off them in 1 week if a fish is hungry they will eat lots of things. it just depends on how much effort you are prepared to put in. for about a month my jags would only eat gudgeons so i didnt feed them for 2-3 days and they they took pellets right away. it might not go that easy for you but a fish can go along time with out eating and theirs lots of ways to get them off slowly intoducing the prepared food with the feeders is also a good way.
