Aw heidi! I'm sorry.. I hope the little bugger pulls through this -- is just having a rough time. I know how attached my mom gets to her fish (and I know how I would be if I had one!!) She is sure people would think she's nuts so I'm the only one she talks to about it...
(But her fish knows her voice - I swear to you. He HATES me and puffs up like I'm a giant beta in his territory... but he swims to mom's fingers and looks like he'd like to be petted.)
Good luck with the little guy. I hope this is just one of those passing things!!!
