hmm... ok, lets see, by my holy bible of fish books, I have calculated below:
Red eye tetras= 4 1/4" ea. @ 8 = 34"
D.Gourami = 2.5" ea @2= 5
Zebra Danio= 2.5" ea. @2= 5
Molly = 4" ea, @1= 4
+________
48" of fish.
Not counting the RTShark @ 4inches or a Rainbow Shark @ 6 inches

EDIT: I can see where some confusion is:
My book has two species of Red-Eyed Tetras. one has the size up to 2 3/4 and the other has it up to 4 1/4. I am going to assume by the photos that the smaller RE tetra is the type that he has, since it looks like the common type found in
LFS.
