I was told this is a Derasa . But Recently I have been investigating and it looks more like a Squamosa
Any Input?

Definitely Squamosa

I think I see “fins” on the shell which would make him a Squammy.
Dersa shell has no “fins”.

T. squamosa will have large scutes on the shell, which I believe I can see on yours.

Better pic of shell, but looks like huge scutes which is squammy.

Awesome guys! This is why I posted it. Thank you for the fast responses.
I will grab another picture later for reference, but yes! It has much larger scutes compared to my maxima.

How are the Squamosas compared to the maximas and Derasas. As far as hardiness, rarity, and requirements.

 

[DeniseAndy]

They are on par with derasa, but grow much faster than any others. They can get large. In 1.5yrs mine went from 2" to 12 " or so.

Um yeah... mine is growing so fast At least 2 scutes in ~7 months
