3yo - Trixie not eating! Help

[GrifTheGreat]

Little guy is already eating and catching tongues and some dubias lol. Which is great. I'll give him the day off today and tomorrow will try to normal feed him again.
Thanks man.

Also there was some formula that was sprinkled on the terrarium coconut fiber thanks to the dubias. Is this a major concern and require a sooner change of substrate or is it fine?

You're welcome.

If possible remove the small amount of formula from the substrate. You don't want it mixed in with it.
