very nice job! you should of painted it black so its not as noticeable!
oh and you should also try to figure out to close the gap where the pvc enters the tank. the aro and gar might or will jump through it.
the krylon fushion spray paint is aquarium safe. ive used it and a lot of mfkers used in their tanks... just gotta let it dry.
very nice. Following this thread gave me the urge to make one yesterday, now I just have to let the paint dry
