here's my young six inch-ish black rhom in his 40 gal long. he really appears to like it alot. his eye is really reddening and he's getting a lot of red under his throat. i took these at night so he may be in dull colors mode. he's a good little rhom and his likes his sand and plants. fed him a piece of catfish before the pics. got him from a lfs early last summer. no idea whatsoever about collection point or age, etc. enjoy.
