I made a post here last week of my porcupine puffer who wouldnt eat, and continued to constantly glass surf. I bought him last monday so this has been going on for a little over a week now. At the time I had tried regular bagged shrimp from the grocery store aswell as clams on the half shell, both with garlic to try and tempt him. No luck. I then tried mysis and brine shrimp because i thought maybe it was too big for him. No luck either. I also have very small peppermint shrimp in my tank with him, so its not like he wouldnt try live food. He tends to stay near either end of the tank and glass surf all day, i have seen him only twice swim throughout the rockwork since hes been in my tank. During which he would tend to hide in the caves. All his tankmates are peaceful, so hes not getting bullied either. At the time i purchased him his fins also looked healthy but as time went on I noticed a bunch of white dots appear on his fins, is this ich? pic included of him with healthy looking fins
