The problem is/was does that mean five 15" fish which is what multiple people thought it meant including myself or fish in the 5 to 15" range? And no anything over 8 to 9" is too big. lol
The new tank dimensions suggested are better but still no on anything over say 8".
I read it as the OP wants a list of fish options that are 5"-15" not realizing that while 135G is a decent sized tank, the dimensions/length matters. Then they shifted to possibilities with a 4 ft tank....in not so many words.
