I bought a toadstool mushroom about a month ago. The tentacles will poke out just enough to see that they exist but I've never seen them actually get any length. Sometimes, the tentacles will be completely retracted, so I can see there is a difference. Is this normal? Does this coral just not have long tentacles?
This is what the coral looked like at the LFS, but i just assumed they'd get longer
