Beef heart is not an ideal food source for axies. Earth worms are good, also salmon pellets, blood worms, brine shrimp are other sources as well.
Why were the axies so skinny from the place you got him? I would have words to whoever sold you that axie. They have obviously not been looked after properly...
im not sure, he could just be really young,
the whole litter were small..
but they have had larger, more developed ones since returning to shop..
im goin to do my best to get him plump..
i got some salmon pellets on my lunch break, il try and keep his diet varied
il keep you all posted on his development.
thanks for all the advice, this place has helped me alot
