Hi, if someone can help that would be great. I have a snooty maori wrasse, have had for about 6 months in my tank with quite a few other fish. I introduced an orange-spot tang about 2 months ago, that is the newest addition, otherwise everything else has been the same. No other fish deaths. All levels fine. Salinity was a little high which we have corrected over the last week, and no other fish appeared to be affected by this anyway. The wrasse is not eating and appears sluggish, whereas normally he is quite firey. He normally loves his prawn pieces or frozen marine food, but lately he has taken it in and appears to be having trouble swollowing, and spits out most of it. He has not eaten much at all for the last week or so. Any suggestions?? Thanks!
