hello i just got a gymnothorax tile and would like some additional info atm the moment he is about 14-15 inches in a 75 corner tank with a salinity of 1.017 in the tank i have some plants black sand and LOTS of manzanita wood in the tank it was my puffer tank but i saw this little guy in my lfs and couldn't leave him and a friend of mine was overjoyed to have the puffers i have a 150 in my garage for him when he gets a bit older the tank has a glass lid and that is pretty much it. Now i have a couple questions what are his possible tank mates? how fast will he grow? and can i keep another brackish water moray with him? this is my first eel and so far i love him any other info is welcome and thanked
