We bought Severus, a new peacock eel, about a month ago. When we brought him home he was very brave and generally lounged on plants. He was also very sneaky and kept jumping into the filter, which made me very nervous. I thought this was because he wanted some peace and quiet. I decided that building an eel tube out of pvc pipe and burying it in the gravel would be a good solution. This required moving all the fish to a different tank for about an hour while my husband and I rearranged things. Ever since the shuffle Severus hides (not in the tube, we took it out after he had not found/used it for two weeks) buried in the gravel. I miss watching him swim, and am not sure how to fix this. Has anyone had a spiny eel become shy after a tank cleaning/revamping. Do you think he will warm up to us again. It has been about three weeks since he started hiding from us, but I now can usually at least find his head sticking out of the gravel somewhere, for the first week or so I was convinced he had jumped out somehow and our dog must have eaten him...luckily he is alive and well. Also, any tips for keeping him out of the filter, so we can bring our water level back up to normal. Any tips/advice would be appreciated.
