sorry, i was gone for a while, i think you answer question about bubbles.
the store in rice lake is pets for you, they only have one salt water tank, not much of a selection. they have had tropical fish for a long time. very clean store and they seem to be knowledgeable, spelling, i think they started the salt water, because there isn't one close by. there was one in hayward last year but they were under, i was sorry to see that happen, but hayward is a small town, i suppose it just couldn't support that type of store.,
