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?

I'm sure other fish are infected, it's just taking them longer to show symptoms because they are complete hogs (clowns). I don't know anyone that can do testing or necropsy, though I'm pretty confident it's internal parasites. All the fish in that tank are from a LFS known for Ich (they tell everyone that "Ich exists in every system...the strong will survive", and every fish I've gotten from them has also had internal parasites. I no longer use them for fish unless I'm in the mood for lengthy quarantine with copper and prazipro.
