So I've got a 55 gal tank with 5 different types of filteration and different types of fish. I've got 2 dinosaur Bichar, 2 peacock eels, 1 tire track eel, needle nose gar, leaf fish, archer fish, and some misc smaller fish that will probably be dinner sooner or later...my main question is all my eels and my bichar move around the tank and eat when offered but my new tire track eel which is slightly bigger then my peacock eels just hides in the corner of a filter and hides. It sits there all day and moves every once in a while...I have feeder fish in the tank for the gar and even tho I have not seen the tire track eat he still seems nice and plump and healthy.he gets defensive and moves when I put my fingers to the glass but goes right back to the same spot. I have not seen any fish mess with the tire track at all but he seems like he just wants to constantly hide behind the filter. Is this normal for tire tracks till then get acclimated to the tank it's been about a week since he was put in the tank. I know something is eating feeder minnowsbecause every morning there are minnows stuck to the filters with bites on them and half bodys so I know it's not the gar. Any ideas? There are lots and lots of hiding places and a while pvc maze under the sand with 5 entrances located all around the tank. The peacock eels use thepvc hides but mainly sit under the sand with there heads out so I know they are not bullying the tire track out of the pvc hides
