I have a Melanarus that's been in my 29g since Jun 2013...original member of the tank. He has always eaten great. This past week we noticed him not eating and appearing VERY thin. We have 2 clowns also in the tank that are eating and acting fine. All levels look appropriate. Internal parasites? He's VERY lethargic... We went to net him out tonight thinking he was dead (he was on his side under a very thin layer if sand) and he swam away. I thought about taking him out and trying PraziPro, but my 10g quarantine has a blue head wrasse in it (waiting to go in the big tank). I highly doubt he would survive the acclimation to that tank at this point. Any thoughts?
