They really don't grow as fast as you would think, but they do get pretty big and it doesn't take THAT long. Mine's grown about 6 inches in 1 1/2 years. Contrast that with the green I have that's grown about 6 inches in 6 months. A 160 would be a great sized tank for one. But it's not something you keep with other animals, like fish, etc. However, I do maintain you can keep a tesselata with other morays, as long as they are of similar size. THey could fight though.
Lion...a 75 for a tesselata?!!!! No!
