Hey everyone, I've read in several threads, that some of you have used ''beef heart'' to feed your pairs, to help plump them up/get them in the mood to breed? Also, do you give it to them, raw/uncooked? I'm assuming yes, that raw is the way to go...I'm strongly thinking of getting some later today, and seeing if my frogs will eat it. I also have pre-cooked, de-shelled, de-tailed/de-vained, frozen shrimp that I can thaw, and cut into pieces...I am open to ideas, or if I can use the shrimp & beef heart, etc... the frogs are used to the Sinking frog pellets that came shipped with them...however, Id like to add some other variety in their diet, something that they will njoy devouring...yesterday I bought nighcrawlers, and red worms..1 or 2 of the frogs managed to down the red worms, but only one...these are all adults, over a year old. Also, do you feed them in the community/group acf tank, or the breeding tank ? I dont know if that makes a difference or not...thanks to everyone, for ANY suggestions on enriching my frogs diets, as right now, they seem to really, only go for the sinking frog pellets they were fed, at the place where I ordered them.
In 1995, an interesting study was done using ACFs being reared in laboratory conditions. I have included the abstract below if you are interested in reading it:

Abstract
Since the European frogs (Rana spp.) have fallen under the German endangered species regulation, Xenopus laevis (South African Clawed Frog) is being used increasingly in animal research and education. Optimal growth rates and homogeneity of groups have not necessarily been attained as little statistical analysis of growth data has been available. Following metamorphosis, an as yet not understood variability of growth is exhibited by X. laevis. In this study the effect of environmental factors on this variability was determined. Feeding, population density, background colouring, water temperature, the availability of hiding places, water level and water care were each examined separately. Development of body weight and body length were recorded. A definite correlation between the feeding programme, population density, cover and water care on the one hand and growth on the other were seen. Of lesser importance were water temperature, water level and background colouring. The observed variability of growth is assumed to also be of ethological origin.
Considering the feeding of Xenopus, the biologists concluded that the frogs should be given a variety of foods, such as, earthworms, slices of raw liver and heart, and dry pelleted food. Live tubifex and blackworms seemed to be the best food for growth and conditioning. They are expensive, however. Out of the four feeding groups, only 2 experienced death - the bovine heart group (3 deaths) and the pelleted food group (1 death). The bovine heart group experienced the poorest growth rate. The death in the pelleted food group was because one frog was not introduced to this type of food in the past. It should be noted that "wild caught" frogs may not adjust well to pelleted foods.
The four feeding groups studied were:
- Xenopus pellets
- bovine heart
- mixed foods
- tubifex
