what the heck is wrong with some people? the guy is asking for advice, and someone getting on his case - - calling him a loser? - - doesn't help
as noted, if you have a "Carpintis", then you have a Green Texas, which will grow to about 6-10", depending if it is a female or male (maybe add an inch or two for some specimens, or if what you have is a "true" Texas (cyanaguttatus)
at that size, a 55G is potentially too small, because it is only about 13" wide, so the fish has limited room to turn around . . . but you already said you will be moving it to a 220G
what I would do is re-post this question once you get the fish into the 220G, at which point you will get a whole new batch of opinionated advice
could you post a picture of the fish? might help people figure out if you have carpintis or cyanaguttatus, for example . . .
