Bought a peacock eel about 3 days ago, the second i put him in he went straight into the gravel, now hes poked his head out and has been out a lil bit at night but within the last 24 hours i havent seen him at all, no nose poking out or anything, checked the floor around the tank and nothing. I have to do a water change today, and was planning to syphon? should i just do a normal water change so i dont disturb him or should i go ahead with the syphoning? obviously ill check the gravel before syphoning just didnt knw if he should be left alone or if a tank check for him is necessary? Hes about 3 to 3 and a half inchs, in a 20 gallon with a gold and opaline gourami, a 3 inch bgk and one pleco. Eventually moving the eel and bgk to a 75 in the near future.
