Recently I purchased a Tig catfish from an online fish store. The fish was sent to me overnight in the mail. Upon arriving it's about 4'' long including the tail (not the streamer).
Ever since it's been in the tank it seems to just keep swimming in place in a corner. It doesn't seem to be to specific as to where it does this, but it seems to be doing it nearly constantly. In addition, I noticed that the gills on the fish seem to be red. I can see a red through the skin (almost as if the skin near the gills is translucent).
I feel like there is obviously an issue but I don't know what. How worried should I be about this? Should I take the fish out and put it in an ISO? I've never kept a Tig before so I'm open to advice.
