Ok guys I need your help and input. I wasn't sure if this is the right spot but I'm super worried about my little wrasse buddy. A bit of history first, I received the fish from divers den on the 28th of last month and started ttm. He did very well through all of it and was pigging out on both mysis and flakes. On the 14th I started the first round of prazipro, he stressed at first but quickly recovered and was doing great again. The 19th was the second round of Prazi and on the same day I noticed two things. The first was that he had white stringy poo (I hadn't seen him poop until that point) to which I assumed he had internal parasites. The second thing was that I saw the spike thing on his dorsal fin (terminal phase McCosker wrasse) looked to be broken midway up. I wasn't sure if it would cause any problems so I decided to keep an eye on him and not treat with antibiotics being that he is already being treated with Prazi. The following day I also started soaking his food in metroplex and focus for the parasites. So pretty much right away I noticed he hated the taste of metroplex, he ate not even half the normal amount of food. Yesterday he ate maybe a bite or two in each meal, this morning he refused all food and I noticed he stayed near the bottom of the tank rather than swimming around like he normally does. I had to leave for work at that point but when I came back this evening he was laying in the bottom corner with his stress pattern going full blown. I didn't soak his food for the evening meal because I think he's getting a little overwhelmed with everything, but he only took one bite and went back to his corner. Now his dorsal spike has me worried also because I can't tell if it's going to get better or if it's infected, which if that's the case should I treat him with kanaplex (that's the only antibiotic I have) or continue monitoring? Im really paranoid about doing too much at once because he's been doing so well up until I started the metro and he messed up his dorsal spike. So props to anyone who read that whole novel and throw whatever advise, opinions, questions you have at me!
P.S. His name is Nessy, short for Nessian the 3rd, and I really love this guy already. I want to do everything I can to keep him well.
