hi there ive just been advised to change my 4 month old veileds food from crickets to hoppers.I done this yesterday and he hasnt eaten any since.I have given him some crickets from a feeder tub and he ate 5 straight away.He also seems afraid of the hoppers he goes a really dark brown when they approach him and moves away from them.should i persist or stick with crickets i have been told hoppers are twice as nutrititional and better for him.Also i seen him eat two lumps of substrate yesterday morning about the size of a small cricket.Can he digest and pass this? .Ive only had him three days and still have alot to learn.I have been given lots of advice from here and find it great that your all so ready with advice.I feel like an over concerned parent.
