ID and advise please

Had my dats for about 4-5 months now, they're a little bigger but their color still is not improving from when I first got them. Also an ID on them would be appreciated. Any advise on getting their colors to come in? they are stable eating krill in a 20gallon grow out. Should I try and put them in my 125 with my silver arowana?

hand size for comparison

Those guys are indos... There are so many things you can try but usually from my experience if you get indos that are unstable they pretty much never stable up unless they are stressed, fighting, etc. A lot of bigger Wild indos stay dark and never really stable.

thanks, hopefully they will magically stabilize lol. As long as they are healthy i guess
