Hairy Mushroom and feeding

[Merman]

Hi
I have read on the internet that you can tell if a hairy mushroom needs feeding by how long its tenticles are. Would anyone be able to elaborate on that? Does it mean if the tenticles are long, they need feeding....?

Im abit confused

Many Thanks
Phil

With mine, I try them every so often, so times they take food, other times they don't,
