some of the time yea but it looks more like s/he will rub up0 against it then swim arong for a little while then come back and do it again, and my mushroom doesnt look lik eit likes all the attention cuz after all the rubbing it kinda shriveled up.
no he isnt always by the shroom. he goes over there rubs up against him for a whjile then leaves and then he comes back in a few minutes and the process begins again.
