yeh its a grade 2 red which surprisingly turns out more yellow than red to my surprise. i was guilty of buying the arow wen i didnt know anything about the species. my excuse is that i was 14 wen i bought him. yeh i prefer not to put decor cause fish like arowanas prefer the open swimming space. my new tank has a black background and floor though. should look cool. i cant really put much decor in my pond either cause my CK and RTCS and TSNs will just uproot everything.
