i got 20 feeder guppies for my brown ghost knife but it looks like my black tetras and betta and angel fish are tryying to eat them and should i let them all go in the tank or keep most of them in my fry pen thingy.
ANY THING HUNGRY lol oscars angels pacus really any other fish larger than the feeders i feed my oscars and my pacu feeders and ocasinally my rainbow and my african chilids eat them too so all i can tell u is get another tank or keep most of them in my fry pen thingy
First of all, if you have a little tank where you can put the feeder guppies, they'll soon be breeding for you and replenishing your supply of live foods. Plus, if you're raising them in your own home, you don't have the same worries about disease and parasites that you have to consider when bringing feeders home from the store.
A good general rule is that any fish will eat any other fish that will fit inside its mouth. I feed young guppy fry to bettas and community fish. I feed full grown guppies to my oscar, my red bellied piranha, and my convict cichlids. It's all a great big circle of life, because my convicts will then turn around and produce larger live foods for the oscar as it grows.
Keep in mind that 20 guppies added to a community tank is quite an increase in the bioload of that tank, unless you have reason to believe they will all be eaten in a very short time frame. Also, before anybody can tell you that live feeders aren't a healthy dietary choice, be sure that you are offering plenty of other foods. Live guppies you've raised yourself ARE an excellent food source for your other fish.
That's a perfect guppy tank!! You only really need a couple of males and the rest females in there. One male can impregnate many females. When my guppy tank sometimes gets a bit too overcrowded, I occasionally feed preggy females to my oscar.
Pretty much any fish will eat smaller fish if it gets the chance. I had a redtail black shark that would sometimes eat my smaller feeder guppies. If I were you, I'd just let them all go in the tank. You're using them as feeders, so it doesn't matter who gets them. When the other fish are hungry enough, they'll get their share. Like Kirsten mentioned, it's best you have a setup where you can breed for your own feeders. That way the introduction of diseases is significantly reduced. That's what I have my 29g for. Although right now that plan has been put on hiatus. My chipokae keeps eating all of them so the rbp's must do without unless I go to the lfs and buy them. When I do, I just buy 50-100 or so and throw them all in there and wait until I go to the lfs again for something I need before I buy more.
Live feeder fish are good nutrition for any fish that can eat them. I fed guppies to goldfish, when I used to have them and my African Clawed Frogs enjoy them, too.
For fish that are too small to eat feeders, live or frozen tubiflex or blood worms are a good substitute.
