That tank can't be 90Gallons, otherwise those are some GIANT harlequin rasbora! Did you mean 90L?
Either way, the aquascaping shows great use of fake plants and decor, infact i'd probably go as far as to say its one of the nicest "fake decor" tanks i've seen in a long while!

p.s. looks like you need some new picture editing software, try the trial version of "paint shop pro" and see if you like it, thats if you can't afford or "get" Adobe Photoshop 7.
