Yeah its a goliath, and dont worry about being harassed by people asking what size tank you have. They dont swim alot anyways unless there looking for food. they never get full grown in cap, alot of them dye off around afoot from loosing it and just killing them selfs. Its not fact but thats what ive seen. But nice fined man!
2 people I know that have had this heppen to them, they say they just loose it for some reason and drill in to the walls over and over agen. IDk about jumping out tho, ive seen mine graze the top of the water but not fully jump.
